Description Paul Hands 2024-04-23 17:54:59 UTC

SUMMARY
Application windows (browser, Dolphin, Konsole) resize to small strip at screen top, and often move to one of three displays - not even the primary - when screen has bee on energy save for some time.


STEPS TO REPRODUCE
1.  Have a bunch of windows open in multiple virtual desktops with multiple monitors.
2. Either lock the screen or let screen saver cut in.
3.  Wait some time and unlock the screens with password

OBSERVED RESULT
Window positions and sizes have changed.

Windows that were on other screens moved to this one

EXPECTED RESULT

This behavior is a major roadblock for using Plasma 6.  I use my Linux box for work, and losing window placement is disastrous for my workflow.  It has become constant since the move to 6.04, but a variation on it was showing in 6.03.
