Bug 457107

Application: plasmashell (5.25.3)

Qt Version: 5.15.3
Frameworks Version: 5.96.0
Operating System: Linux 5.18.8-200.fc36.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora release 36 (Thirty Six)"
DrKonqi: 5.25.3 [KCrashBackend]

-- Information about the crash:
Some monitors tend to do a power cycle when connecting to the AMD GPU. In that case it's first visible, then hides, then becomes visible to the PC again. This not only makes Plasma crash while screen is in its DPMS state, but also shifts all windows to the main display.

Info: one of my displays is scaled to 120%

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
