Public bug reported:
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:
1) Boot Ubuntu
2) Close lid and let the laptop go to sleep mode
3) Open the lid and login
4) Start a random video on Youtube/VLC/Totem
5) Switch to fullscreen
-> Immediate freeze of the screen
Workaround after the video froze:
1) Press ESC key to leave the full screen mode of the video
2) Close the lid
3) Wait until the laptop goes into sleep mode
4) 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 tell me this:
gnome-shell[1744]: meta_window_set_stack_position_no_sync: assertion
'window->stack_position >= 0' failed
