Created attachment 127659 [details] Screen layout that exhibits the problem SUMMARY I have a secondary screen with a panel on the top of the screen that is set to 'Always Visible' and windows cannot go on top or below. For whatever reason, windows on my primary screen (physically to the left of the secondary screen) act as if the panel is actually on the primary screen instead of the secondary screen. Not sure if related, but the 'Application Launcher' widget that's in the panel, and its tooltip, opens on the primary screen as well. None of the other wigdets on that panel open on the primary screen but correctly open/tooltip on the secondary screen. STEPS TO REPRODUCE 1. Make a panel on the top screen edge of a secondary screen that is 'Always Visible' and windows cannot cover or go below 2. Have a window on the primary screen (I used 'System Settings') 3. Try to move the window to a portion of the screen that would be covered by the panel (if it was on the primary screen) OBSERVED RESULT The window attempts to maximize, rather than move. If maximized the window doesn't cover the entire screen, leaving a section of the wallpaper visible. EXPECTED RESULT The window can move there without maximizing. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (available in About System) KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.69.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION Not actually sure it's a plasmashell bug or KWin, please move as needed. I'm also somewhat available to try out/make patches, assuming that I can figure out building the relevant component. I've attached a screenshot of my screen setup, notice the problematic panel on the right screen at the top, and a maximized window on the primary screen that doesn't quite cover the screen.
I've revisited this and the issue is that whenever I drag the panel using the "Screen Edge" manipulator, there's a little bit of the panel (a couple of pixels maybe) on the screen to the left (if the panel is on the rightmost screen, the leftover pixels are on the middle screen). The panel has the "never be covered by windows" setting enabled, so now the middle screen has a black bar. I'll edit the title accordingly, and I'll look around later to see if this has already been addressed somewhere else.
Update: After updating to Plasma 5.19.0, I have not seen this bug in Wayland sessions (though I can't confirm if this is true of 5.18.5 or earlier as the Wayland session was unusable in my setup before 5.19.0).
Can confirm this still occurs to me on the X11 session in Plasma 5.19.0 Software versions: KDE Plasma: 5.19.0 KDE Frameworks: 5.70.0 Qt: 5.15.0 Kernel: 5.7.2-arch1-1
I am Having the same problem. My panel is at the bottom. It is set to "Always Hide". But any other window like Chrome Browser or any other Maximized window will always goes below the panel.
