Description eleung 2024-06-25 17:20:53 UTC

SUMMARY
If you have Spectacle opened before you shut down, the fake session restore introduced in KDE 6.1 will open it for you automatically during the next boot, causing the screen to freeze and dim if you are using rectangular capture by default with Spectacle. This happens on Fedora KDE 40.
(I posted this in r/kde and was told to submit a bug report)

STEPS TO REPRODUCE
1. Set Spectacle to use Rectangular Region capture as default
2. Open Spectacle 
3. Reboot the machine (or whatever method that triggers the session restore)

OBSERVED RESULT
Screen freezes and dims after login as Spectacle waits for user input

EXPECTED RESULT
No such behavior. Maybe blacklisting Spectacle from session restore by default?

Heh oops. This is probably an app that should be excluded from fake session restore. Not sure if we have the power to do this in the app itself, or if it'll have to be added as an exception in the fake session restore feature, which would be a bit ugly.
