SUMMARY Sometimes, when I login (a logout usually fix this), the windows selects the WRONG panel to minimize, on the wrong screen. If I open a new instance of a program, it also open in the other monitor. NOTE that the screens are configured in the right position, a re-login workaround the problem when appear. STEPS TO REPRODUCE 1. Sometimes, at login, the it happens 2. Move windows to other screens or 1. Create new windows instances. OBSERVED RESULT This video display the problem https://www.youtube.com/watch?v=ybgrIUFj7xs&ab_channel=FrancoGast%C3%B3nPellegrini EXPECTED RESULT Windows should minimize to the correct panel and screen SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE NEON stable KDE Plasma Version: 5.20 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.0
I work everyday using KDE, and 2 times per week, this error appear. Sometimes, when it happens, discord minimized icon get duplicated on both panel (both screen) but the minimization animation goes always to the other screen. Also note that I manually invert the position from both monitors, so KDE rearrange them on login (but it seems that sometimes fail like the video).
Is this X11 or Wayland?
x11
Does this happen only with Discover, or with other apps? Can you test with Dolphin and a non-KDE app like Firefox or Chromium?
it happens with ALL programs. It's like the panel get inverted between the 2 screens, and some app like discord, get duplicated on both panels. Note that I have checked the option "show only icons from current screen", but when this bug appear, it seems to get ignored, or a swap between screens.
How odd. Thanks for the additional info.
Today at boot, all notification started to appear on the second monitor, the first one shows a black background, but correct widgets, and all new windows starts to appear as programs from the second monitor. No minimized icons on the first one, ignoring my manual windows rearrangement. There's a serious problem when using 2 panels with two different task manager, showing different monitors.
Created attachment 132929 [details] inverted monitors manually
I attached what I changed in my monitors, because my physical arrangement. Today it appear again at fresh boot, and it seems that the applications are ignoring that configuration when spawning windows
why the status is marked as "need info"? what do you need?
All good, thanks.
Today, it get worse. Both monitor get inverted like the attached image "inverted monitors manually". But this time, they get totally inverted, not only panels. I just need to go to that menu again, and change the position manually to actually represent my monitor arrangement. Also my 165htz goes to 60. It seems that the menu forgot all my monitor configs.
Today, the 2 screen get partially merged, and one background screen can sometimes appear on the second one. Also, all notifications and program appear on the wrong screen. A quick fix is to reboot session 1 or 2 times, and then it work for a week or so. I managed to capture a video (notice that one screen is black because the background merged on the second screen): https://youtu.be/xMm27C9m8b0 Operating System: KDE neon 5.20 KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 Kernel Version: 5.4.0-58-generic OS Type: 64-bit Processors: 6 × Intel® Core™ i5-8400 CPU @ 2.80GHz Memory: 22.9 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 630

window minimization and the calculation of where to locate the animation are done by KWin; moving there.
Problem continues... and I have to reboot 3 or 4 times everyday until the screens decide to select the correct monitor. Very frustrating.

I can offer a better workaround: run `kquit5 plasmashell && kstart5 plasmashell` to restart plasma. The issue seems to stems from the fact X11 has not specified order in which screens are declared and plasma expect this ordering to be constant. This concerns Wayland as well for the same reason.
I am having the same issue however, windows will seem to minimize to whichever task manager I last interacted with. For example, if I were to unpin and pin a random icon in the task manager on my left (secondary) monitor then all minimize window animations will go to that screen and if I unpin and pin on my right (primary) monitor, they will always animate to minimize there. Although, sometimes this randomly gets swapped every now and then.
Problems continues. When boot, the main monitor background becomes black (but with panels), and all windows get minimized into the second monitor Operating System: KDE neon 5.24 KDE Plasma Version: 5.24.1 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 Kernel Version: 5.13.0-30-generic (64-bit) Graphics Platform: X11 Processors: 6 × Intel® Core™ i5-8400 CPU @ 2.80GHz Memory: 22.9 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 630

Yeah could you check again with Plasma 5.24.3 when it's released in three days?

Thanks.
