The problem can't be mutter issue 199 because the fix (mutter!431) was already released in mutter 3.32. And you have mutter 3.36 already in Ubuntu 20.04. So you already have that fix and I've just confirmed it by looking at the source code too.

This is the bug - report in Mutter: - - https://gitlab.gnome.org/GNOME/mutter/-/issues/199 - - It was fixed, I believe this was the fix: - - https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/431 - - I think this fix (and all related, if there are more) should be - backported to Ubuntu 20.04.
