Positioning is handled by the backend, rather than in the UI. If you hover over this "invisible display", does the cursor change to a grab cursor? Also, it would be useful to see any errors that are spat out to the console. You can do this by running: kcmshell6 kcm_kscreen in a terminal. The output of that might reveal some UI errors that are causing this. -- You are receiving this mail because: You are watching all bug changes.
