SUMMARY STEPS TO REPRODUCE I haven't be able to reproduce. It seems to happen when a lot of Chrome/Chromium tabs are opened or possibly more than one program opened. The bug happens when logging out without closing the any window opened. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 20.04 (available in About System) KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 ADDITIONAL INFORMATION
This is just the apps blocking the reboot process by doing their own housekeeping. *** This bug has been marked as a duplicate of bug 188476 ***
But the bug also happens when I close all windows
This problem began recently on my system, but I'm not exactly when, possibly after upgrade to Plasma 5.19. This is one more recent regression related to login/logout. :( SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.19.2 KDE Frameworks Version: 5.71.0 Qt Version: 5.15.0
I still have this problem sometimes in 5.21.4 D:
This was fixed very recently in a newer version of Purpose (which is a framework, and not a part of Plasma. It was 5.80 or 5.81 IIRC.
Great! Here I have Frameworks 5.80.
Oops I closed the wrong bug report. :(
Understood. Also, sometimes the desktop turns all black but some windows are still opened. I get an impression that this happens mostly with GTK apps, but I might be wrong.

When some GTK app is opened, the logout process is even more slow.
I can confirm that. Not sure there's anything we can do from our side if non-KDE apps are the culprits though.
Is weird because if I hit the close button inthe GTK app (in that black screen where there's only the GTK app window), the shutdown process flows normally.
Right, the GTK app is somehow not responding whickly enough to the quit request. I don't know if there's anything we can do here, or if it's purely a bug in those apps or in GTK itself.
Hmm, this is also happening when no Qt apps are opened here. But the odd thing is that GTK apps gets stuck in the black screen when logging off, whereas Qt apps don't.
I'm getting a similar issue where the screen will turn blank with just the cursor for a number of seconds before the system logs out / reboots / shuts down.
Could this be related to that bugfix of KDE Connect that was made for 5.24?
There isn't anything we can do at the KDE level here when 3rd-party apps take a long time to quit properly, but we can hide it better. That's tracked by Bug 188476 *** This bug has been marked as a duplicate of bug 188476 ***
