Empty main screen when i upgraded to Ubuntu 22.04

The --no-sandbox flag will probably fix this:

Anki shows a blank window

You could create a shell script to start Anki with the --no-sandbox flag: #!/bin/bash export QT_QPA_PLATFORM=xcb anki --no-sandbox QT_QPA_PLATFORM=xcb prevents Anki from running in Wayland. That’s optional of course, but I recommend it because Wayland isn’t a good experience yet.

Also, Wayland has some issues, so I recommend using x11 (xcb) for now.
