** Description changed: [ Impact ] When using software rendering on Xorg (so usually just in VMs), some parts of app windows may fail to redraw. https://gitlab.gnome.org/GNOME/mutter/-/issues/2880 [ Test Plan ] - TODO: Figure out a minimal test plan that doesn't require modifying - code. + 1. Set up a virtual machine without graphics acceleration. + 2. Log into 'Ubuntu on Xorg'. + 3. Open Settings > About and verify Graphics = llvmpipe and Windowing System = X11. + 4. TODO [ Where problems could occur ] The fix adds a new synchronization point between the compositor and X server. This should be inconsequential, although there is a "sync ring" in mutter used for this, and if a mistake occurs there then other parts of the desktop could appear to stop responding in Xorg sessions. [ Other Info ] This is a regression that started in 3.37.3 via 551101c65cda.
