Screencast capture in Full Screen Exclusive Mode on XWayland

[Philip Race]

I'm seeing this on a fully patched Ubuntu 22.04.02 which has 
"42.0-3ubuntu2" .. which I suppose is < 42.3
so could well be that's the issue.
Seems like we need to move up to more recent distro of something with a 
later gnome.

FYI Alexander found the problem went away on VirtualBox if he disables 
3D Acceleration
but that isn't a general workaround ..
