Bug 473931

Application: spectacle (23.04.3)

Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.4.11-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
Honestly happens pretty much every time I disconnect HDMI that I hardly notice it. Pretty graceful failure and just pops up in the taskbar and I usually ignore. Possibly related to some larger infrastructural Wayland/Pipewire issues I'm seeing that are causing massive heatups of my CPU cores, especially with things like X forwarding over ssh, remote connection software (mostly connectwise that I have to use for work until I integrate a better solution for our company), scaling certain apps, etc. Likely in large part due to the amount of weird configurations I have going on for work and general exploration. That one is really a pain in the ass and I basically have to dump all my screen connection software to keep my CPU cores from getting well above 80C and throwing the fans on warp speed 9. If contacted about this I'm glad to generate dumps for that, no real crashes so it hasn't popped up to prompt a bug report and I've been too busy to track it down and report manually.

The crash can be reproduced every time.

-- Backtrace:
Application: Spectacle (spectacle), signal: Segmentation fault
