Screencast capture in Full Screen Exclusive Mode on XWayland

[Philip Race]

FYI  I just tried a suggestion from Olivier to use invoke lg and execute
a command which will do something like (if I head it right) bypass the 
compositor for a full screen window

Meta.disable_unredirect_for_display(global.display)

This does fix it on Ubuntu 22.04 .. so I think the suggestion was that 
if this fixed it, then
it is probably something Ubuntu-specific rather than a general Gnome 
problem.
