Created attachment 97176 [details] .Xsession-errors When logging with multiple monitors attached, KDE starts with the login manager's screen configuration (cloned displays) and displays its splash screen. Shortly before showing the desktop it then switches to my usual desktop screen configuration. During the switch both screens flicker for ~0.5 seconds (99% sure that this is graphic driver related however), then the splash screen appears again. After the screen configuration has been changed, it will not show the splash image ("the big K") on the primary monitor anymore: Only the progress bar and the background image will remain. Video of this behaviour (explains it much better): https://storage.xmine128.tk/s/r4yTiGisMp8eznn I can provide additional debugging information and test (and possibly write) patches.

BTW: The exact same thing happens when running `ksplashqml --window` after log in and changing the same of the appearing splash screen window using the mouse cursor.
