Screen freezes when switching video to fullscreen
Hi.
The screen freezes when I switch a running video into fullscreen mode. It happens with Gnome Totem, VLC, Firefox, so the issue is not connected to a certain app.
I can hear the audio playing in the background while the video output gets stuck. The keyboard keeps working but switching to another app via keyboard doesn't work because the screen keeps stuck with the video.
Way to reproduce:
- Boot laptop
- Close lid and let the laptop go to sleep mode
- Open the lid and login
- Start a random video on Youtube/VLC/Totem
- Switch to fullscreen -> Immediate freeze of the screen
Workaround after the video froze:
- Press ESC key (As if you would usually leave the fullscreen mode, however, the screen will stay stuck)
- Close the lid
- Wait until the laptop goes into sleep mode
- Open the lid and login again
Step 1) is necessary to 'leave' the fullscreen before going to sleep. Otherwise after sleep and logging in again the screen gets stuck again immediately because the video is continued in fullscreen.
Syslog tells me this:
gnome-shell[1744]: meta_window_set_stack_position_no_sync: assertion 'window->stack_position >= 0' failed
I am not sure if this is a Ubuntu specific problem that's why I am posting it here to hear your opinion about it. If you need further logs, I can provide.
