--- Comment #2 from Pawel <bednarczyk.pa...@outlook.com> --- I have a feeling this happens when the mouse cursor crosses from a maximized app or the desktop to the panel. In my case I have a single panel at the bottom of the screen and work with maximized apps such as Thunderbird or Firefox. -- You are receiving this mail because: You are watching all bug changes.
