Empty dropdown menus

[Sebastian Jacobs]

Some snap apps installed on my system show not clickable dropdown menus without text in options. Not all dropdown menus are affected and sometimes the app crashes when I open these empty dropdown menus. Affected dropdowns are directly in the app or in the app's menu bar.

snap 2.53.1
snapd 2.53.1
series 16
ubuntu 21.10
kernel 5.11.0-37-generic

Snaps with the problem: Standard Notes and Beekeeper Studio
Snaps that seems to not having this problem: Firefox and Postman

Hi,
Do you see any apparmor denials related to these apps on the affected system? e.g.

$ journalctl |grep DENIED

Also, checking the (dis)connected plugs of those snaps (with snap connections <snapname> command) may give some clues.

$ journalctl |grep DENIED
