Steps to reproduce (only tested on X11): - Find a program which is able to toggle Fullscreen Mode via a shortcut, e.g. 'mpv' video player uses 'f' key - Run the program and hover over the close button, until a tooltip appears - Press the shortcut to switch to Fullscreen Actual result: - The tooltip stays on screen until it is clicked away Expected result: - The tooltip hides It also does not hide immediately when the window is resized programmatically, but a small move of the mouse over the decoration fixes it. The tooltip probably needs to re-evaluate mouse position if either the mouse moved, or the decoration moved programmatically or toggles due to fullscreen change.
cannot reproduce on Arch Linux. Probably fixed by https://cgit.kde.org/kwin.git/commit/?id=c44adda40f47418ce6eea974b2a3c3b1e77fa205
Yeah my fix should have fixed that one as well.
