--- Comment #4 from farsee...@gmail.com --- Thanks for the hint. It seems the window is owned by plasmashell, and it is from the panel (even with an empty panel). If I put an empty panel on the top or left side of my screen, the black window will appear. If the empty panel is on the right or bottom side of my screen, the black window is gone. -- You are receiving this mail because: You are watching all bug changes.
