--- Comment #4 from Hexagon <apri...@posteo.net> --- I just discovered, that it does not only occur in Firefox but other applications too and seems to be a general problem of KWin, therefore I changed the ticket title. It also happens on Signal. To reproduce it there send a video into a chat and start playback of it, enter fullscreen playback and move the mouse. You see the same glitches and mouse cursor size changes as in Firefox playing a YouTube video. -- You are receiving this mail because: You are watching all bug changes.
