UI interference in Arch | How to clean crash leftovers ?

[t8ja]

kernel 5.15.53-1-lts
obs-studio 27.2.4-1
After selecting a leftover "output device" in the tray options, the screen flickers and UI elements grow a few seizes too big.

Possible problems are listed in the README but there are no proposed solutions.

How to get rid of the leftovers after a crash ?
How to reset the UI alteration without restarting lightdm "sudo systemctl restart lightdm" ?

OBS crash sometimes kills the headphone output of the targeted App.
Running OBS after a crash, I hear the App on headphones, the App is selected but no audio is picked up i OBS / VU meter shows nothing.

Also, running multiple instances of firefox while playing audio in two simultaneously seems to cause a crash at the moment audio is initiated in the one not being targeted.
