Package: libmutter-7-0
Version: 3.38.3-2
Severity: normal
X-Debbugs-Cc: bernha...@mailbox.org
Dear Maintainer,
I tried to replicate #982572, therefore
setup a qemu VM with two qxl devices [1].
This is currently running a kernel 5.2 due to #983934.
Inside I have trouble with mouse input,
therefore activated remote access by keyboard.
(Unfortunately can just access one of the
two screens with this method.)
On that screen I did some resolution changes and
window moves, then gnome-shell crashed.
I have not yet tried to reproduce this or cannot
say if this happens because of this special setup.
Found also no other down- or any upstream bug about this.
It seems that we get in [3] a nullpointer for "monitor_mode",
that gets dereferenced later.
In [2] are the last frames of the backtrace, complete
in attached file.
Kind regards,
Bernhard
