Thanks for the bug report. I believe this is a known problem with the mutter Wayland backend. It was mentioned by the developer just this week: https://gitlab.gnome.org/GNOME/mutter/-/issues/2127#note_1373187 Although that bug was closed when the user's main problem was found to be an unrelated crash.
