Sometimes, when I click the title bar of an unfocused window, it causes the window position to change. I can't see a pattern except, perhaps, that it only happens to windows for which I've set special window settings, in particular, for the position. It does not happen when focusing the window in any other way.
@Michael D, can you please make screenshot the affected window settings - in order to reproduce this issue
Created attachment 114461 [details] Special window settings for position
I'm only forcing the window position. No other window rules have been set.
I think I see the pattern: it happens only to applications using xwayland.
This issue report is quite old. Can you please confirm, that it still persists with KDE 5.23?
Cannot reproduce anymore on wayland, Plasma 5.23.2.
Thank you for your response. I'll mark this issue resolved.
