Hello,
I am not involved in maintaining this package, just looking through some crash
reports.
My attempt to resolve the dmesg lines from the crash to a source line
information led me here:
clutter_paint_context_get_redraw_clip at
../clutter/clutter/clutter-paint-context.c:140
https://sources.debian.org/src/mutter/44.8-3.1/clutter/clutter/clutter-paint-context.c/#L140
137 const cairo_region_t *
138 clutter_paint_context_get_redraw_clip (ClutterPaintContext
*paint_context)
139 {
140 return paint_context->redraw_clip;
141 }
This function name leads to following bug report, which sounds interesting:
https://gitlab.gnome.org/GNOME/mutter/-/issues/2876
And which got fixed by this merge request:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3283
First upstream release containing this fix would be 45.1,
unfortunately not yet in unstable or testing.
But a proper backtrace might still help to confirm, if this crash is
really the same which is described in the mentioned mutter bug report.
https://wiki.debian.org/HowToGetABacktrace
Simplest version could be to install systemd-coredump
and inspecting the journal after a crash.
Kind regards,
Bernhard

I tried with the newly uploaded version, and managed to get some further information. Attempting to cast a window, or the whole screen, appears to work now, but with 8-10 seconds of lag, making it unusable. (I'll report that as a separate bug.) Attempting to cast a virtual monitor still causes a crash. Here are logs from that attempt: Feb 02 00:28:36 o gnome-shell[1083]: Added virtual monitor Meta-0 ...

Both this version and the version you tried worked for me using the Chromecast protocol. Could you try to provide a bit more information? What version of GNOME Shell are you using? Are you using X or Wayland? Is there anything unusual about your system you should mention? If you are using Shell extensions, have you tried without them? Does it still crash if you try while logged in as a new user? Try looking through your systemd log with journatlctl to see if there are related errors. Thank you, Jeremy Bícha
