Comment 10 for bug 2000644

I see the same on Jammy, like the others it is reproducible easily by hitting the meta key and exiting from there in any way (hit ESC, select anything to start, ...).
Sadly setting fixed workspaces (10) did not work around the issues for me, like it did for others.

Occasionally (seems to depend if this issue races with something else as it seems more likely if the system has more apps running and me doing more things) I also get the stuck-desktop experience out of that. Usually starting with the mouse not being able to click everything anymore and a while after with a totally stuck desktop (not even ctrl-alt-f# gets me out anymore).
That "stuckness" if it is still phase-I (mouse can't clock it all) sometimes resolves itself after a few minutes - no log entries in journal when that un-stucking happens.
