Title:
gnome-shell crashed with assertion failure
"!xcb_xlib_threads
Reverted mutter to focal-updates stock, rebooted into 5.8.0-33, repro'd
again :( so we're back to the hypothesis that there's something wrong in
5.8.0-33. Sorry for the noise, I'm trying to debug this as best as I
can.

Never mind, I think mutter 3.36.6-1ubuntu0.20.04.2+lizf1 is busted,
please disregard :)
on the plus side I have a reliable trigger.

Started seeing this recently with 5.8.0-33 after a few minutes logged
into either Wayland or X11 session, regardless of other activity on
system, but does not repro once I downgrade kernel to 5.8.0-31.
Gnome shell version 3.36.4-1ubuntu1~20.04.2 has been the same
throughout. Mutter likewise on 3.3
