2026-07-27Hide a window only when srdwm knows it has not drawn, not when a lookup says sosrdusr1-1/+1
Regression I introduced two commits ago, reported live: "I can click close where the button would normally be and it does close, but it is still invisible." The gate that stops an empty frame being drawn before a client paints asked the renderer, from inside the render loop, whether a window's surface had a buffer attached right now - and treated "no" as "do not draw". That question is only meaningful for a native xdg-shell toplevel. An XWayland window's surface state does not describe it the same way, so the answer came back no on every frame and the window was never drawn again, while srdwm's own hit-testing carried on working perfectly: an invisible window that still takes clicks, which is a worse failure than the empty frame it was meant to prevent. Inverted to the fail-safe direction. `new_managed_window` - the one path that creates a native toplevel - puts the window into `awaiting_first_buffer`, and `commit` takes it out on the first commit that carries a buffer. The render and capture paths test that set and nothing else. A window is now hidden only when srdwm itself put it there, so no window whose plumbing works differently can be hidden by a lookup that did not apply to it: the XWayland map path never touches the set, and neither can anything else. The buffer question still gets asked, but only in `commit`, about a surface it was just handed, where it is the right question. Verified both halves: an ordinary spawn still shows no frame before content (26 captured frames with content, 0 without), and the only way into the set is one line in one function.
2026-07-26Draw a window's content from the same rect as the frame around itsrdusr1-1/+6
Reported live: "resizing shrinks/grows only the right side", and "the titlebar seems separate when resizing, it doesn't size at the same time". Both are one bug. Every decoration - border strips, titlebar, shadow -- is drawn from `frame`: the client's last committed size, anchored to whichever edge the drag is not holding. The content was drawn from `geom`: this compositor's live drag target, which moves on the same frame the pointer does. A client is always at least one commit behind a drag, so for that whole interval the two rects disagree, and the window is drawn as two pieces that move independently - the stale buffer sliding left with the pointer, carrying its old width, while the border it belongs in stays where the committed size puts it. Dragging a left edge therefore looked like it moved the right one. All three content paths now position from `frame` (both udev render loops and the winit one). Outside a resize this changes nothing at all: `committed_frame` only ever corrects the far edge, so `frame.x`/`frame.y` and `geom.x`/`geom.y` are the same value. Measured in a nested compositor, driving a real left-edge drag with the virtual-pointer tool and sampling both the model's target rect and the rendered pixels at the same moments: the content sits exactly one border width inside the border on both sides in every frame, the right edge holds at 830 throughout, and the left edge tracks the pointer (305, then 405). The earlier decorated-window run measured the same thing for the titlebar: its left edge moved with the window, its right edge did not move at all.
2026-07-23Do not draw a window before its client has painted anythingsrdusr1-0/+4
Reported as "before a window spawns, the border corners look funny". A toplevel is placed, sized and decorated the moment its role is created, which is well before the client draws. srdwm was rendering it from that moment, so what appeared first was an empty frame: border, titlebar and shadow standing around bare desktop, at the guessed 800x600 placeholder size, with nothing inside. When the real buffer arrived the frame snapped to the real size. Measured in a nested session, capturing a cold terminal's spawn with grim: four consecutive captured frames spanning 540ms showed a complete red border with zero client content inside it, at 642px outer height, which then settled at 610 - a jump of exactly one TITLEBAR_HEIGHT. After this change the same capture has no such frame at all: every frame that shows a border shows content in it, and the height does not change afterward. Two parts: - Nothing is drawn for a window that has never committed a buffer. All five paths that draw a frame agree on this - both udev render loops (Pixman and GPU), the winit render loop, and both screencopy paths, so a screenshot cannot show a frame the screen does not. - The open-slide starts at the first commit that carries a buffer rather than at role creation. A cold terminal took ~800ms to paint, long enough for the whole tween to finish against the empty frame, so the window simply appeared, already at rest, with no animation at all. It now animates where it can actually be seen. The answer latches once true (windows_shown_once), so a window that has legitimately shown something is never hidden again by this however its buffer state changes. A window that cannot be resolved to a surface counts as drawable, deliberately: this hides a window only on positive evidence that it has never drawn, so nothing whose surface plumbing works differently - an XWayland window - can be hidden by a lookup that did not apply to it. Same shape, and the same reason, as sync_layer_visibility's own has_buffer branch, which layer surfaces have had all along. 533 tests pass, clippy clean.
2026-05-11Fix spawn placement under the top bar, add per-window minimum sizes, and ↵srdusr1-1/+10
clean up maximize Four reports after restarting into today's build, with a screenshot. The screenshot was measured, not eyeballed: top bar y=0..29, a 4px accent border at y=30..33, titlebar from y=34, bottom border at y=1027..1030, and 49px of bare desktop below it. Windows spawning too close to the top bar. A remembered position was validated only by asking whether it landed on some monitor's full_geometry, which includes the strip a top bar reserves, so an app whose remembered y was small reopened with its titlebar under the bar. That is why it was "sometimes": it depended on the stored value, and the live store holds wezterm at y=44 and firefox at y=69 against a 30px bar. Remembered positions are now clamped into the monitor's usable area. Placement not surviving a logout. Window memory does persist, but five of the eleven entries in the live store were saved with a second monitor attached, at x >= 2000. Those points match no current monitor and were discarded outright, falling back to a fresh cascade, so those apps appeared to remember nothing. Such a position is now clamped onto a monitor that exists instead. Per-window minimum sizes. One global floor is wrong in both directions. Three sources now, in increasing precedence: the global floor, the client's own declared minimum (xdg_toplevel.set_min_size or ICCCM hints), and a min_width/min_height window rule overriding both. A rule wins permanently -- the backend refreshes the client's declared minimum on every decoration redraw and must not undo a deliberate override. Maximize, three faults in one report. A maximized window now draws no border: its edges are the screen's edges, and the only place maximize stops short is the bar strip, which is exactly where the measured line was. maximize_geometry_for no longer subtracts a bottom-anchored dock's exclusive zone, so maximize runs to the bottom of the screen and the dock floats over it; top, left and right are still honoured. general.maximize_covers_dock = false restores the old behaviour. With the border gone the window sits flush under the bar instead of with an accent line crowding it. Verified: seven new tests on the real numbers from the live store, and maximize geometry measured live in a nested instance (a window maximized on a split half reports exactly that half's rect). NOT confirmed on screen: the border removal and the dock behaviour - the nested backend has no bar or dock to reserve a zone, and an attempt to check the border produced a failing control, since srd set border_width only affects windows created after it. 515 tests pass, clippy clean.
2026-04-27Build the eight asks recovered from the previous session's transcriptsrdusr1-0/+20
The punch list was not the whole record. These are the owner's own typed requests, read back out of the previous session's transcript rather than guessed at, then each checked against the code before being treated as open. Three they suspected were already done really were: dialogs already had a Close-only titlebar, inactive dimming already existed, and the corner resize hitbox had already been tuned. Snap layouts on drag, asked for twice. Edge snapping worked but committed silently on release with nothing shown first, so there was no way to know it would happen or where. A translucent drop-target preview now follows the drag, and throwing the pointer at a monitor's top edge drops down the existing six-cell grid to aim at. The preview calls the same snap_zone that end_drag does, so the two cannot disagree. Two defects found by screenshot before landing: moving down onto the flyout closed it, and its labels overflowed at a fixed cell width - the same "text goes out of view" fault already fixed once for the context menu. New File now offers real types, chosen by extension, with the de-duplication counter placed before the extension so the file stays what it says it is. Refresh re-reads init.lua and fires a new srd.on("refresh") handler instead of only re-scanning the icon grid. What refresh means beyond srdwm's own config stays the config's decision. general.config_reload_on_write (default on) applies an edited config on save, via an mtime sweep rather than an inotify watch: no new dependency, same behaviour on every target, and unaffected by editors that write through a temp file. A real bug behind "what happens when our config fails": you lost every keybinding. do_reload cleared the binding, handler and repeat tables before re-executing and never restored them, so a syntax error left neither the old config nor the new one, and the only key still working was the reload combo nobody thinks to press. The tables are now restored on any failure and config errors reach notify-send, not just the log. srd.lock() and a default Mod4+Ctrl+l binding: the built-in lock screen could not be reached from Lua at all. Native rather than shelling out, because a lock key that shells out fails silently when the binary is not on PATH. Default bindings added for srd.window.move and a dynamic/tiling toggle, both of which existed with no way to reach them, plus srd.layout.get() so the toggle reads the live workspace rather than the configured default. Dialogs open centred, and are excluded from remembered geometry in both directions - that table is keyed by app_id, which a dialog shares with the window that spawned it, so dialogs inherited an unrelated position and size and then overwrote it with their own. theme.decorations.title_bar.button_mode (dynamic by default, or fixed) drops the Maximize button on a window whose client pinned min == max size, where pressing it can do nothing. Maximize is removed from the slot list rather than skipped in place on both the render and hit-test sides, so the remaining buttons close the gap identically; three tests pin that agreement, which is what fails silently when it drifts. Also: the nested backend's screencopy pass now draws both menus, the flyout and the drag preview. Four investigations in one day started from a screenshot missing a tier, so that pass carries an explicit list of what it still omits and the on-screen loop points at it. 512 tests pass, clippy clean.
2026-04-20Confirm Nemo's popup works; fix the two bugs that hid it, and shadow bleed ↵srdusr1-2/+7
across a monitor seam Nemo's right-click context menu was the last open punch-list item, parked twice as untestable. It works: verified end to end in a throwaway nested compositor, menu and submenu both, at the correct position and stacking. The popup path itself needed no fix, so the POPUP-GEOM-DIAG/POPUP-GRAB-DIAG diagnostics are removed. Two real bugs turned up in the way of testing it. zwlr_virtual_pointer was a silent no-op on the winit backend. Every Motion/MotionAbsolute handler read UdevState::bounds() behind an early return when state.udev was None, and that field is Some only for the DRM backend. The protocol advertised its global, accepted create_virtual_pointer and accepted every request, then discarded all motion with no error and no log. That is the backend a nested instance runs on, so the only safe way to drive a throwaway compositor - a Wayland client of that compositor, which cannot reach any other session, unlike ydotool's /dev/uinput writes - did not work at all. Bounds now come from WindowManager::monitors() when udev is absent; both backends fill that list from Platform::monitors(). The winit backend's screencopy pass rendered no popups and no shadows. It re-renders the scene offscreen, and that second scene was missing tiers, so grim on a nested instance reported the opposite of the truth: a menu drawing perfectly on screen photographed as absent. The DRM backend never had this, since it serves screencopy from the on-screen frame it just drew. Border strips are still missing from that pass, called out in the code rather than left silent. Also fixed, from the "windows show a bit in the other monitor" report: shadow_rect expanded by SHADOW_SIZE on every side with no monitor-boundary awareness, so a window flush against a seam put its 24px shadow strip on the neighbouring screen. shadow_rect_clipped clips to the bounding box of the monitors the window's geometry actually touches - not just its assigned one, since a window straddling a seam really does occupy both and clipping there would cut its shadow off mid-body. The bitmap's own extent stays unclipped, because the src rectangle indexes into it; only the fragment list is clipped. Six tests on the incident's own numbers. Not confirmed on screen: the nested backend cannot produce a second monitor. New tool: tools/virtual-pointer-click, a scriptable virtual-pointer driver that acknowledges each command after its round-trip, so a test script can put a screenshot between a move and the click that follows it. 489 tests pass, clippy clean.
2025-11-20Redesign the native lock screen: clock/avatar header, on-screen keyboard, ↵srdusr1-1/+13
wrong-password shake The native lock UI was a flat bordered rectangle with three left-aligned text lines and no shadow, clock, or identity marker - reported directly as looking unfinished. Splits the redesign across a new transparent-canvas header (time, date, circular avatar, username) above a redesigned, centered password box with a real drop shadow and a dimmed placeholder prompt, plus a genuine on-screen QWERTY-shaped keyboard with working Shift/Backspace/Return/Space and real click hit-testing shared with the render path via one `lock_stack_layout` function, and a damped-sine shake on a failed attempt. LockConfig gains show_clock/show_keyboard/avatar_bg, each independently srd.set-able and documented in a new theme.lock.* section in DEFAULTS.md. native_lock_render_elements now takes one NativeLockFrame struct instead of positional buffer arguments now that it composites five optional layers instead of two. Full workspace build/test/clippy clean (152 wayland tests, +6 new).
2025-08-15Add real desktop icons plus right-click desktop/icon context menussrdusr1-0/+22
Closes "right-click on bare desktop" - previously a true no-op, nothing rendered above the wallpaper at all. Requested directly: a real desktop "just like windows does" - Home/Computer/Trash plus one icon per real ~/Desktop entry, individually draggable with persisted grid positions, double-click to open, right-click menus (per-icon "Open" plus "Set as Wallpaper" for image files when general.wallpaper_command is set; bare desktop "New Folder"/"Refresh"). Architecture mirrors the existing context_menu.rs/snap_flyout.rs "compositor-owned floating UI" pattern: desktop_icons.rs (data model, grid layout, filesystem scan, hit-test), desktop_icons_state.rs (JSON persistence, same shape as monitor_layout.rs), desktop_menu.rs (the new right-click menu, reusing decoration::render_context_menu's existing rasterizer), state/desktop_icons.rs (CompState glue: rescan/select/drag/ open/persist), and a new decoration::render_desktop_icon rasterizer -- hand-drawn glyphs, since no PNG/SVG decoding capability exists anywhere in this workspace. Wired into both render loops (udev and winit) above the wallpaper and below every window, and into input/pointer.rs's button/ motion handlers for selection, drag, double-click, and both menus. Four new config keys: general.desktop_icons (default true - a directly requested, purely visual feature, unlike the opt-in-while-experimental general.gpu), general.file_manager, general.desktop_icon_single_click, general.wallpaper_command (all default off/empty). Deliberately out of scope for this pass, stated up front: move-to-trash and "Empty Trash" (destructive, no confirmation-dialog primitive to gate them on yet), filesystem watching, multi-select, per-mimetype icon art, icons on any monitor but the primary one. 124 wayland-crate tests (up from 106), full workspace build and clippy clean.
2025-08-09Fix interactive-resize border/shadow lag without the OOB risk that sank the ↵srdusr1-3/+15
first attempt effective_frame_of now returns the live drag target while a window is being interactively resized (same change as the reverted first attempt), but two things make it safe this time instead of reintroducing the out-of-bounds texture sample that reversion was for: - Every src crop rect built from a window's frame width in udev/render.rs and winit/render.rs (titlebar, top border strip, bottom border strip) is now clamped against DecorationSignature's own recorded width/ border_width - the bitmap's actual last-built size - before reaching MemoryRenderBufferRenderElement::from_buffer, which does not itself validate src against the real texture size. This is a structural floor independent of timing, not a repeat of the previous unsafe approach. - handle_pointer_position now calls redraw_decoration_buffer once per resize motion event (throttled to 60Hz via a new CompState::resize_redraw_at), closing the lag at its source instead of only catching up on the next real client commit. This also fixes the shadow bitmap's identical commit-vs-live-position gap for free, since redraw_decoration_buffer rebuilds all three bitmaps together. Updates the TODO.md entry for this bug with the full before/after.
2025-05-23Clamp the winit backend's own CSD margin offset to non-negative toosrdusr1-1/+8
Same fix as the udev backend's matching content-position code: a real CSD shadow margin (dwindow.geometry().loc) is never negative, but a live Firefox window was observed reporting loc = (-10, -10) despite sync_geometry's tiled-state hint telling it to reserve no margin at all. This path (rounded_content_element, a live GLES shader rendering the client's own texture directly, not a separate pre-shifted buffer) doesn't have the udev backend's double-application bug, but it shares the same single-subtraction call and so needed the same clamp.
2025-03-03Fix VT-switch DPMS blank-screen and CSD corner-crop staircase bugssrdusr1-7/+42
VT-switch resume: reasserting the CRTC's mode-setting state was never enough on its own - display power (DPMS) is separate KMS state, and nothing here ever touched it after a real switch-away-and-back. Page flips kept succeeding with zero errors logged for the rest of a real 30+ minute session while the panel itself simply stayed dark, which is what actually explains a user report of the screen and keyboard input never recovering after one VT switch. Sets DPMS-on unconditionally on every resume now, the same property zwlr_output_power_v1 already writes for an explicit client request. Corner rendering: both backends' side-strip crop (the fix that keeps a window's flat left/right border strips from poking a solid-coloured square through the top/bottom strip's own rounded curve) only ever activated for `w.decorated` windows. An undecorated/CSD window's crop depends on its *content* actually getting masked to match - the winit backend never checked that at all, so every CSD window with a nonzero border_width got the uncropped, "staircase" artifact unconditionally, confirmed live via a highlighted border colour and raw pixel sampling. Ported the udev backend's own `border_curve_is_safe` check (decorated OR content-will-be-masked) into winit, using the cheap "does this surface have subsurface children" test both content- masking code paths already gate success on, rather than duplicating either one's real (comparatively expensive) rendering work just to probe it. Full workspace build + clippy -D warnings + test suite (378 tests) green.
2025-02-18Fix clippy warnings surfaced by the mergesrdusr1-1/+1
Pre-existing issues in the uncommitted rust-rewrite work (unused imports, over-arity glyph-drawing functions, a couple of complex inline types, or_insert_with(T::default) instead of or_default(), and one unsimplified test-only arithmetic expression), plus two imports left unused by switching to or_default(). None of these are behavior changes. Full workspace build + clippy -D warnings + test suite (378 tests) all green after this.

2025-02-17Checkpoint: today's fixes before reconciling with the rust-rewrite worktreesrdusr1-8/+62
Fixes a live-reproduced VT-switch busy loop (failed page_flip retried with no backoff), shadow rendering bleeding onto occluding windows unclipped, and a winit-backend buffer-age correctness bug that left stale cross-window pixels on screen. Committing before merging in the much larger uncommitted rust-rewrite worktree, which independently touches several of the same files - this is the pre-merge baseline to diff against, not a claim that these are the final versions of these fixes.
2025-02-15Checkpoint: preserve all uncommitted rust-rewrite worktree worksrdusr1-21/+91
Safety commit before reconciling this worktree with main, which has diverged with its own separate fixes today. Nothing here is reviewed or curated yet - this exists purely so none of this work can be lost to a git operation, disk issue, or worktree cleanup while that reconciliation happens.
2025-02-04Fix CSD windows rendering with a wallpaper-visible gap at their cornersrdusr1-1/+9
srdwm never read xdg_surface.set_window_geometry anywhere. A CSD client (GTK4/Firefox) declares its real visible content as a sub-rect inset within a larger buffer that also reserves an invisible shadow margin - that margin stays reserved in the buffer even once the tiled-state hint tells the client to stop drawing the shadow itself. Every render path was positioning content at the client's raw buffer origin instead of subtracting that declared offset, leaving the margin's width/height as a gap with wallpaper visible through it at the window's top-left corner. Confirmed by pixel-diffing the gap against the real wallpaper at that exact screen position: an exact match, ruling out "just the client's own dark theme." Fixed in three places that have to move together: udev/render.rs and winit/render.rs's content-positioning code, and sync_geometry's space.map_element call. That last one matters as much as the other two - it's what smithay's Space (and therefore click hit-testing) reads, so a render-only fix would have traded a visible gap for an invisible, same-size hit-test offset in the other direction. Also applied to the new capture-workspace off-screen render for the same reason. This likely also explains real dropdown/context-menu misplacement (and the clicks landing on the wrong spot) in CSD apps: popup positioning anchors against the same window position this fix corrects.
2024-12-24Accumulate wayland-crate additions: capture rendering, focus/Space sync, VT ↵srdusr1-3/+41
resume, plumbing Bundles the remaining wayland-crate changes built up here, touching both backends (udev and winit) and the shared input/rendering code: - udev/capture.rs: off-screen Pixman render of an arbitrary (not necessarily on-screen) workspace's window content to a PPM file -- what crates/core's capture-request queue drives, for a workspace switcher's thumbnail previews. wlr-screencopy structurally can't do this (it can only see what an output is presenting), which is why this exists as a separate render path rather than reusing it. - input::focus_window now also raises the window in smithay's own Space, not just core's stacking order - Space is what actually renders on top and what pointer hit-testing reads, so any focus path that skipped this (an IPC "focus" dispatch, concretely) left a window genuinely focused while still rendering, and receiving clicks, underneath whatever was already topmost. Both backends' poll loops now re-sync this after any IPC mutation. - udev/session.rs's VT-switch resume fix (drains a stale pending page flip before reasserting CRTCs) already has its own earlier, cleanly isolated commit - not duplicated here. - Assorted decoration/cursor/rounded-corners/output-management/ screencopy/XWayland changes and their cross-backend wiring. Coarser than the repo's usual one-purpose-per-commit convention, deliberately - see the core-crate sweep commit's own message for why.
2024-08-23Round the bottom border strip's corners to match the topsrdusr1-12/+24
MISSING.md listed the border frame's bottom/left/right strips as staying square while the top one (and the titlebar above it) rounds -- "unrelated to client content rounding... not attempted." The left/ right strips genuinely can't participate (border_strips' geometry has them span only the height between the top and bottom strips, no corner to round), but the bottom strip is exactly the same shape as the top one and had no reason left to stay square. decoration::render_border_bottom mirrors render_border_top exactly (round_bottom_corners mirrors round_top_corners), cached the same way in a new border_bottom_decorations map, and drawn in both render loops via the same all-or-nothing occlusion check the top strip already uses - pulled out of the left/right strips' per-fragment occlusion splitting into its own dedicated bitmap path, matching top's existing trade-off (cropping a rounded bitmap's source rect per fragment is real extra work for a strip this thin) rather than inventing a new one. One real bug caught before it shipped: round_bottom_corners' corner- centre math (height - r - 1) panics on unsigned underflow whenever the radius clamp lands on the strip's own full height (a real, common case - a 2px-thick test strip hits it immediately). Fixed by computing the centre as a signed offset instead, mirroring how the existing dx/dy distance math already avoids the same class of issue.
2024-08-03Fix doc-comment file references left stale by today's six module splitssrdusr1-13/+13
~17 comments across the codebase still pointed at udev.rs/winit.rs/ state.rs by their old flat-file names after those became udev/, winit/, state/ directories - found while auditing what this work rushed, since the split verification (function/struct-name diffing, full test suite) checked structural correctness but never comment accuracy. Updated each to either the specific new file (e.g. "see state.rs's REPEAT_DELAY" -> "see state/mod.rs's REPEAT_DELAY", "udev.rs's monitors()" -> "udev/platform.rs's monitors()") or the bare module name where the reference was already generic ("the udev/winit backends", not a specific location).
2024-07-31Split crates/wayland/src/winit.rs (889 lines) into winit/srdusr1-0/+331
Pure reorganization, no behavior change - verified by diffing the function-name and struct-name sets before/after (both identical) plus a full cargo test pass. mod.rs keeps the module doc comment, imports, WaylandPlatform's struct definition, and TARGET_FRAME_TIME, plus mod declarations. The rest splits by concern: - connect.rs: connect(), the ~200-line setup/init function. - run.rs: accept_clients, pump_winit - the small per-poll pair. - render.rs: render_frame, the per-frame render loop (left as one intact ~330-line function, same reasoning as udev's render.rs: its structure is deliberate and already documented inline, not a target for further decomposition in a pure reorganization pass). - capture.rs: capture_offscreen, the screencopy path. - events.rs: handle_winit_event. - platform.rs: `impl Platform for WaylandPlatform`. No tests module existed in the original file, so none was split out. A handful of methods/functions (accept_clients, pump_winit, render_frame, capture_offscreen, handle_winit_event) went from private to pub(super): called across what are now sibling submodules, which Rust's privacy model doesn't let see each other's private items.
