Hello, These are the steps to reproduce it for both .deb and snap versions. Once Thunderbird is open, right click around the tab bar and choose customize. Once in that window, choose either to show title bar or hide (depending on what you have already done prior). Close the customize window, but you will notice there are two dots beside Thunderbird icon on Ubuntu dock indicating it has two windows open. If you click on Thunderbird the UI locks. If you by chance do not click on the icon on Ubuntu dock you can clear off the extra dot by restarted GNOME UI by typing 'r' in run dialog for x.org. Not sure if this is reproduceable under Wayland.
