-- Information about the crash:
While spectacle was open in the background, I used the KDE system settings to disable the primary monitor and exclusively use my second monitor. This is when spectacle crashes.

The crash can be reproduced every time.

Application: Spectacle (spectacle), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
