SUMMARY
A window rule with "Apply initially" seems to not be applied when KWin is
restarted and the app reconnects.
It is applied when the app is started normally
STEPS TO REPRODUCE
1. Set a window rule to put a window on a certain virtual desktop and choose
"Apply initially"
2. Start the Qt app and notice how it shows up on the correct desktop
3. Kill kwin and have it restart
OBSERVED RESULT
The window shows on the current virtual desktop
EXPECTED RESULT
The window shows on the virtual desktop that the window rule says it should
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: git master as of 2025-11-13
Qt Version: 6.9.2
ADDITIONAL INFORMATION
Of course only works with Qt apps that can survive a compositor restart. I only
tested "virtual desktop" rule.
