--- Comment #17 from maderios <leoutat...@gmx.fr> --- Yes, it works with VLC in any case but it doesn't work with SmPlayer/ MPV or Avidemux It's clearer now: issue happens while other X session is running with Firefox launched To reproduce: 1) start X session in tty1 for user-1 2) launch Digikam 3) open video file from Digikam with VLC, SmPlayer or Avidemux : it works normally Then : 1) from tty2, start other X session for user-2 and launch firefox 2) go back to user-1 3) open video file from Digikam with VLC: it works normally 4) open video from Digikam with SmPlayer/ Mpv or Avidemux : it doesn't work -- You are receiving this mail because: You are watching all bug changes.
