Description z.hanham00 2025-02-12 05:52:24 UTC 
Application: kwin_x11 (6.3.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.2
Frameworks Version: 6.10.0
Operating System: Linux 6.12.11-200.fc41.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora Linux 41 (KDE Plasma)"
DrKonqi: 6.3.0 [CoredumpBackend]

-- Information about the crash:
I have a Nvidia gtx 1660 SUPER, and two screens connected via HDMI and DP.
When starting plasma x11 session, it works fine on my primary screen (DP) with the other screen off (HDMI).
When I try to switch screens using Meta+P or any other method such as xrandr or nvidia settings, I either get a totally blank screen, or a black desktop with a mouse and windows visible, but with screen tearing when I move them.
Interestingly enough, the wayland plasma session has worked flawlessly for me since I installed Fedora 41 KDE, even with a nvidia card. Only the X11 session has this issue

The crash can be reproduced every time.
