Created attachment 151469 [details] screenshot SUMMARY I have a two monitor setup: Main (right) 1440p 165 Hz running at 165 Hz. Secondary (left) 1080p 144 Hz running at 144 Hz. The problem is that, at random times, sometimes after exiting a full screen app, sometimes after the logon screen... The windows on the right screen will maximize to cover the lower 3/4 of the screen. The width remains normal, mouse movement and wallpaper are unaffected and so are full screen applications. Trying to move a window to the empty area causes it to maximize. Behavior traced to Kscreen 2 STEPS TO REPRODUCE Happens at random after system changes the screen by : App going full screen. System going into Log on screen. System Start. OBSERVED RESULT Windows maximize to 2/3 of the screen. EXPECTED RESULT Windows should maximize to the total screen area. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.97.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION Garuda O.S. Bug observed in conjunction with the already reported automatic screen shutdown for energy saving Bug: Automatic screen shutdown doesn't work and instead sends all my windows to the left screen, remaining both on. Disabling Kscreen 2 prevents both Bugs from happening.
Are you using the X11 session or the Wayland session?

Can you try the Wayland session and see if it works there for you?
(In reply to Nate Graham from comment #3) > Can you try the Wayland session and see if it works there for you? Tried Wayland. Turning off the screen for Energy saving works but, not only migrates all windows to the left monitor, it also crashes some apps or the system itself. In addition to that, Wayland brought some other new glitches that made me return to X11. I didn't see the maximization bug happening, but given the randomness of its occurrence and that I could only stay in Wayland for 24 hours before returning to X11, I wouldn't assume that it does or not occur in Wayland.
Thanks. I think there is a very high chance that this issue will have been fixed by work that just want in yesterday for Plasma 5.26: https://invent.kde.org/plasma/kwin/-/merge_requests/2573. Can you test again once Plasma 5.26 is released, or using Neon Unstable?

I will try when Plasma 5.26 is released and update with my findings. Thanks.
