I know bugs like this are frustrating, but increasing their severity does
not help to find their root causes and fix them.

The gnome-shell and mutter packages are still at the same version in
stable and testng/unstable, but all the recent reports of GNOME Shell
crashes on suspend, lid-close or monitor plug/unplug seem to have
been with testing/unstable, not stable, so I think this is probably a
regression in some other component, or a GNOME Shell or Mutter bug that
is triggered by a change in some other component. (Unless someone has
information to the contrary?)

If that theory is correct, then selectively downgrading gnome-shell
dependencies to the versions from buster might help; if it does, reporting
which downgrade(s) were successful would be very useful in tracking down
what is wrong and how to fix it.

Based on https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932428#10
I would start with the Mesa libraries, GLib or GTK 3.

This *is* useful information: it links the recent reports of crashes
on suspend/lid close with other recent reports of crashes on monitor
hotplug. Please could you send an example backtrace to confirm that it's
the same?
