More info: The bug affect all snaps but not ordinary executables. All snaps launch distorted. After a recent reboot I tried several times to launch Firefox, every time the bug appeared, and all my tabs where unreadable. Then I started Thunderbird (which is NOT a snap) and clicked on a link in a mail so that a new tab opened in Firefox. Suddenly Firefox was normal, and all tabs (also the old ones) where readable just fine! Other snaps e.g. chromium still launches with the bug. When staring the snap "openscad-nightly", the initial splash screen (Welcome to OpenScad) is normal, but when I click on e.g. "Open Recent" I get a distorted window. So far I haven't been able to recognize any message on stderr that are common when launching snap programs, but there are plenty of apparmor="DENIED" in dmesg, if that's any clue.

It seems to work fine under the corruption, but it is completely unusuable. The tar version of Firefox works fine. In the attached screenshot you can see the snap version of Firefox (corrupted) and the tar version of Firefox (working fine). I tried uninstalling (with --purge) and reinstalling and refreshing firefox to no avail. All other applications, including 3D games, are working fine. I am using an AMD RX5500 with default mesa drivers.
