Summary: Black screen after certain kind of actions [NVIDIA]
[Animations]

Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kwin_wayland (6.6.0)
ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.23.0
Operating System: Linux 6.18.10-200.fc43.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 43 (KDE Plasma Desktop Edition)"
DrKonqi: 6.6.0 [CoredumpBackend]
-- Information about the crash:
After actions like alt+tab (thumbnail grid swticher), screen edge (action
Overview) or activating Tiles editor (meta+t) it some sometimes (more often in
past few days) results in immediate black screen. I then have to log to another
TTY and send `SIGUSR2` (hint from claude) to `kwin_wayland` process to restore
the desktop, though sometimes I just `reboot`.
This does not always happen.. I start to notice that some things enhance the
chances... I feel like screen dimming when AFK results in higher chances...
maybe even when bluetooth headphones are connected (but that seems a little
far-fetched).
GPU: Nvidia GTX1060 6G
