--- Comment #11 from David Edmundson <k...@davidedmundson.co.uk> --- Kwin tracks if an internal window has focus and sends the mouse event to the window directly. Bypassing QWindowSystem. QMenu at some point for the "sloppy timeout" references a global position from: QGuiApplicationPrivate::lastCursorPosition.toPoint(). This is set on every proper QPA but not on kwin as kwin has been bypassing normal mouse actions So Qt thinks the mouse is not over any menu and closes it. -- You are receiving this mail because: You are watching all bug changes.
