Today this problem happened on patched system.
But case was different:
1. launch Firefox
2. switch firefox in fullscrenn mode by F11
-- here GUI hung and gnome-shell process begin consume 100%
I got backtrace from gnome-shell process and after it Xwayland begins consume
100%

All backtraces attached below.
