Upstream has already "fixed" it by reverting the change in a later release:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3030 Although this seems to be because they were waiting on a fix in Xwayland version 23.1.0 which Ubuntu 22.04 doesn't have yet. It looks like the downside they were trying to avoid was: > sending modifiers to clients prevents direct scanout for DRI3 clients via Xwayland so it was just to make full screen gaming performance better. If you can live without that optimization then you should keep MUTTER_DEBUG_SEND_KMS_MODIFIERS=1. Starting in 23.10 we have the best of both worlds so you won't need to choose anymore. ** Changed in: mutter (Ubuntu) Importance: Undecided => Medium ** Changed in: mutter (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2026886 Title: [amdgpu] google chrome hardware acceleration broken on 42.9-0ubuntu2 Status in mutter package in Ubuntu: Triaged Bug description: This morning, I upgraded gnome-shell and gnome-shell-common from 42.5-0ubuntu1 to 42.9-0ubuntu2, and I noticed that chrome no longer renders properly. Notice the missing image header on the Ubuntu website and the garbled right click menu here: https://i.imgur.com/BPnqfVG.png I downgraded gnome-shell and gnome-shell-common version to 42.0-2ubuntu1, restarted gnome, and the rendering issues went away: https://i.imgur.com/CzEPgqY.png I upgraded gnome-shell and gnome-shell-common again to the latest and the rendering issues came back. Going to chrome://settings/system and disabling hardware acceleration fixes the rendering issues (but now I don't have hardware acceleration).
