SUMMARY When the user uses the window control menu (Alt+F3) to hide a window from the current activity, the window lingers in the current activity until the user switches to another virtual desktop and back. This bug does not occur with kwin 5.24.5. STEPS TO REPRODUCE 1. Open multiple activities 2. In a window in one activity, press Alt+F3 and choose to show it in another activity 3. Press Alt+F3 again and choose to hide it from the current activity OBSERVED RESULTS The window is still shown in the current activity, but you can't interact with it. This 'ghost' disappears when the user switches to another virtual desktop and back EXPECTED RESULTS Window should be immediately hidden from the current activity if the user has chosen not to show it.
