Bug 495679

Application: spectacle (23.08.5)

Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 6.4.0-150600.23.25-default x86_64
Windowing System: X11
Distribution: openSUSE Leap 15.6
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
I have a somewhat contorted display area with a very high res center screen, and 1920x1080 screens on either side. I am trying to capture the window in the center screen and have done this many times, but today getting captures are just giving crashes. Not sure what has changed, but I DO have completed captures perhaps 1 in 5 times.

The crash can be reproduced sometimes.

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