From 61d01bb79c6882c950f45a1176ba1f30fbbd4824 Mon Sep 17 00:00:00 2001 From: srdusr <99972264+srdusr@users.noreply.github.com> Date: Sat, 9 Aug 2025 00:57:00 +0200 Subject: Fix interactive-resize border/shadow lag without the OOB risk that sank the 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. --- crates/wayland/src/udev/platform.rs | 1 + 1 file changed, 1 insertion(+) (limited to 'crates/wayland/src/udev/platform.rs') diff --git a/crates/wayland/src/udev/platform.rs b/crates/wayland/src/udev/platform.rs index 691c8de..a4a72a0 100644 --- a/crates/wayland/src/udev/platform.rs +++ b/crates/wayland/src/udev/platform.rs @@ -240,6 +240,7 @@ impl UdevPlatform { border_top_decorations: HashMap::new(), border_bottom_decorations: HashMap::new(), decoration_signatures: HashMap::new(), + resize_redraw_at: None, hovered_titlebar_button: None, shadow_buffers: HashMap::new(), rounded_corners_program: None, -- cgit v1.2.3
