That should be included in 42, and does look related. There seems to
have been a regression
(https://gitlab.gnome.org/GNOME/mutter/-/issues/2282) that I seem to
have fixed
(https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2462). The fix
was backported to 42.3. What version of mutter does your system have
installed?
