Description shinjii 2023-04-03 09:37:45 UTC

STEPS TO REPRODUCE
1.  Upgraded KDE from 5.27.2 to 5.27.3
2. Upgraded Nvidia official drivers to 530.41.03

OBSERVED RESULT
I don't know if it's bug from KDE Plasma or Nvidia Drivers because both were upgraded on the same time.
Anyway - on Plama Session in X11 when I restart notebook - second monitor is black - when I move cursor on it - it's waking up lol and when I'm logged in when I try to open some windows/programs on second monitor - they  only show after I move cursor to that second desktop... so it's not visible if I'm not move it in... it's weird - it looks like screen is freezing while cursor is not on that second screen/desktop.... because when I try for example play video from youtube on that second screen it's freezing while i'm not moving mouse on that desktop lol.... weird.

EXPECTED RESULT
Refreshing/not freezing as on 5.27.2 : )

Linux/KDE Plasma: Fedora 37

UPDATE: it's working fine on Wayland Session so it's something with X11.
