Unless your log mentions "clutter_actor_get_real_resource_scale" or "guessed_scale", I fear most people will land here by accident. The reason seems to be that our bots don't adequately distinguish between different assertion failures, which is bug 1982283.
The log in comment #20 doesn't even seem to be an assertion failure, but some unknown Xwayland crash/error: Mar 01 09:49:15 corrado-n2-nn-0220 gnome-shell[1443]: Connection to xwayland lost Mar 01 09:49:15 corrado-n2-nn-0220 gnome-shell[1443]: Xwayland terminated, exiting since it was mandatory so please open a new bug for that if you can find the /var/crash file for it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1959507 Title: gnome-shell crashed in clutter_actor_get_real_resource_scale() with assertion failed: (guessed_scale >= 1.f) Status in gnome-shell package in Ubuntu: Confirmed Bug description: Hi, I'm starting a VM Ubuntu 22.04 on QEMU/KVM and this alert appears.
