Fixed in mutter 42.1 but we should probably patch it in sooner than that
for jammy.

Title:
gnome-shell crashes (fatal error logged in create_fallback_offscreen)
when attempting to enable second monitor on second GPU (Nvidia >= 495)
in a Wayland session
Status in Mutter:
Unknown
Status in mutter package in Ubuntu:
Fix Committed
Bug description:
This is on my weird desktop setup, with one monitor plugged into an
AMD card and one into an NVIDIA card.
When using the Wayland session, by default Shell will come up on the
monitor connected to the AMD card, and the second (NVIDIA) monitor
will be blank. Attempting to enable the second monitor in Display
Settings will immediately and reproducibly crash gnome-shell.
This is trivial for me to reproduce, so if you need patches tested I
can easily do so.
