Bug 423527

SUMMARY

When the user tries to log out, if a window raises an exit dialog (e.g. save/discard changes), the user hears a sound and the window raises. This works when there are multiple such dialogs on the current virtual desktop, OR only 1 dialog on a different virtual desktop. However, various issues crop up when there are multiple dialogs and at least 1 is on another desktop.

STEPS TO REPRODUCE
1. On the current virtual desktop, load program window A
2. Configure A so that it will raise a dialog on exit (e.g. KWrite w/ unsaved changes)
3. On a different virtual desktop, load program window B
4. Configure B so that it will raise a dialog on exit
5. Initiate logout

OBSERVED RESULT

All panels, etc. vanish. After ~1 second, a sound plays and a confirmation dialog raises for A. Close the dialog. No 2nd sound plays. After ~10 more seconds, the other virtual desktop appears; the confirmation dialog for B appears to be raised, but not focused. After ~1 more second, logout completes.

EXPECTED RESULT

In sequence, for each confirmation dialog: a sound plays, the virtual desktop changes (if necessary), and the window/dialog is raised/focused.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.70.1
KDE Frameworks Version: 5.70.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION

The exact behavior differs somewhat based on how the dialog-raising windows are distributed across virtual desktops, but the rule appears to be that everything works fine for multiple dialogs on the current virtual desktop. As above, if in addition there's 1 dialog on another virtual desktop, it doesn't get a sound and doesn't appear until just before logout.

If there are no dialogs on the current virtual desktop, but multiple dialogs on a different desktop, a sound plays, but the view stays on the current virtual desktop. 10 seconds later, the view changes to the other virtual desktop, the dialogs are visible but possibly not focused, then logout finishes a second later.
