SUMMARY After unplugging the external display, a Wayland window from a Chrome PWA is out of the visible screen area. Screen configuration: (1) Laptop internal screen, eDP, 2880x1800, 175%, off when (2) is connected (2) Monitor, DP, 3840x2160, 150% Status of the window from KWin debug console: bufferGeometry: -1572,316 1386x871 clientGeometry: -1556,326 1354x829 frameGeometry: -1556,326 1354x829 height: 829 width: 1354 pos: -1556,326 rect: 0,0 1354x829 size: 1354x829 x: -1556 y: 326 windowType: NET::Normal The sequence of actions leading to this issue: 1. Connect the monitor 2. Switch to another user (screen configuration is the same) 3. Unplug the monitor and close the lid (put the laptop to sleep) 4. Open the lid (wake up) 5. Switch back I am not sure if user switching is crucial but they are included for completeness. STEPS TO REPRODUCE Not sure. EXPECTED RESULT The window should be in the visible screen area. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.80 KDE Frameworks Version: 5.249.0 Qt Version: 6.7.0 Kernel Version: 6.7.0-arch3-1 (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon Graphics KWin is (probably) at 9f10d5d79f. ADDITIONAL INFORMATION I also noticed that after unplugging the external monitor, non-maximized windows are only partly inside the visible screen.
Created attachment 165029 [details] Screenshot when moving the window Using the "Move" action in the task manager menu, I'm able to move the window back into the screen with arrow keys. The move cursor is outside the window, as expected.
Switching users seems very relevant indeed. Can you try again without switching users and see if it still happens?
It still happens without switching users. It is also a bit random - I cannot seem to figure out if there is a relationship between a window's position in its original screen, and where the window is after unplugging the monitor.
Thanks. I've got a theory: when this happens, did some part of the system fail to notice that the external screen was unplugged? Some signs that this might have happened? - The cursor can move offscreen into the area that the disconnected screen was occupying - The system fails to go to sleep when the laptop lid is closed, and the Power and Battery widget displays a message about this in its header area
This happens to me very frequently, without any user switch. Simply unplug a screen when multiple windows are open: some windows are moved from the unplugged screen to the visible one, others remain invisible.
