--- Comment #4 from Martin Flöser <mgraess...@kde.org> --- That one was tricky: the problem is that the stacking order for X11 fullscreen windows does not depend on the active window but on the most recently activated client. The most recently activated client is a concept I thought we do not need for Wayland. On X11 when activating a window a request is sent to the window and it takes focus. So KWin only marks it in the most recently activated client list and removes it from there when it actually gained focus. Have a patch for the problem, now thinking about a unit test ;-) -- You are receiving this mail because: You are watching all bug changes.
