I am experiencing an issue after update to 22.04 (UbuntuStudio with KDE Plasma): login (and lock) page are white, only the logo and text space are visible.
Everything is working fine, so not really a big deal, but I'd like to solve the issue.
I noticed something similar here (but the solution suggested there did not work for me):
Deepin/Ubuntu white/black screen on login/lock pages (particularly with Deepin greeter)_
The problem occurs only at the login (initial or in case of opening/closing sessions) and not in case of unlock open session. This makes sense as it is related somehow to graphic drivers.
any tips? thanks
