UPDATE: Apparently this is a long-standing and pervasive issue in the mutter package: https://gitlab.gnome.org/GNOME/mutter/-/issues/1419 https://gitlab.gnome.org/GNOME/mutter/-/issues/230#note_1551972 https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2092 https://gitlab.gnome.org/GNOME/mutter/-/issues/1418 https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1778983 https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1574251 https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1927948 The second link has an explanation that sounds plausible. The issue can occur under a wide range of circumstances from suspend-resume (which I have since witnessed) or just locking the screen and not just when KVM switching a KVM. Unfortunately there is zero activity on the issue.
