That causes an unnecessary performance hit, especially noticeable when using a remote session. Upstream bug: https://gitlab.gnome.org/GNOME/mutter/-/issues/3630 Upstream fix: https://gitlab.gnome.org/GNOME/mutter/-/commit/030270ba3bf14b23a2d7a5371cf158ff2591f327 [ Test Plan ] 1. Set up an Ubuntu system and log in 2. Launch the Looking Glass debugger by pressing `Alt+F2`, typing `lg`, and pressing Enter 3. Navigate to the "Flags" tab in the top right corner of the debug window 4. Scroll down and enable the `PAINT_DAMAGE_REGION` flag. By enabling this flag, a red overlay will appear to show regions where the screen is being redrawn and helps visualize framebuffer damage. 6. Drag a window across the screen 7. Verify that the red overlay only covers the window rectangle rather than the whole screen On the first drag the bug is expected to still be reproducible, but all subsequent drags should not trigger the bug. [ Where problems could occur ] mutter is the Wayland compositor library that provides graphics and inputs for the GNOME desktop, thus is a critical component. Problems could manifest with the action of dragging a window not working anymore, or sudden log-out if gnome-shell crashes.
