Description equeim 2025-02-02 19:45:29 UTC 
SUMMARY
After logout/reboot/shutdown happened while Android Studio was running, launching it again fails with error about stale lockfile ("~/.var/app/com.google.AndroidStudio/config/Google/AndroidStudio2024.2/.lock" in case of Flatpak version). So it is probably not terminated 

STEPS TO REPRODUCE
1. Launch non-Qt XWayland app (e.g. gedit with GDK_BACKEND=x11 or Intellij IDEA)
2. Do something so that it asks for confirmation when you try to close the window
3. Log out of Plasma

OBSERVED RESULT
App does not show confirmation dialog, Plasma logs out immediately

EXPECTED RESULT
App shows confirmation dialog, Plasma does not log out until the app is closed

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1

ADDITIONAL INFORMATION
I can reproduce this with Intellij IDEA Community, Inkscape, gedit.
Kate (when running with QT_QPA_PLATFORM=xcb) is not affected.

Sorry for botched summary, IDK how to edit it.

Hi - I can reproduce this on Plasma 6.2.5, KDE Neon VM.

I was initially thinking that this was a duplicate of https://bugs.kde.org/show_bug.cgi?id=477579 - however, unlike what was described in that issue, OnlyOffice also fails to prompt about unsaved work - there might be some connection still?

Thanks for the bug report!

CCing the David Squad to see if it's feasible for us to do anything about this, since it's rather bad and could cause data loss.

As far as I can see, they dont connect to ksmserver.

Does this work in a X11 session?

The behaviour seems the same in X11 session, non-Qt apps are just killed even if they have unsaved data.

Nothing we can do there then.
