Public bug reported:
I have a recurrent crash of gnome-shell that happens without any
specific action. This crash has appeared since I've upgraded from 24.04
LTS to 26.04 LTS. My assumption is that issue is somewhere in the
graphics stack (mutter/wayland/nouveau) and gnome-shell is just the
victim. I've tried deactivate mutter's experimental-features and it
didn't change anything.
