Public bug reported:

[Description]

During video playback a very disturbing bug occurs: the video area is always on 
top every other window.
The video also won't scale when changing the size of the player window.
This is not player-specific as both SMPlayer and VLC are affected.
The bug doesn't register on screenshots so I had to take a photo of the screen 
to illustrate:

Temporary workaround found in that redhat bug report to enable proper video 
playback in SMPlayer (Point #6 of Eric Lavarde's steps to reproduce):


- Open SMPlayer, go to Options -> Preferences
- Go to "Advanced", then to the "Options for MPlayer/mpv" tab
- add -vo gl to the (empty) option list

** Affects: xserver-xorg-video-intel (Ubuntu)
     Importance: Undecided
         Status: New

** Package changed: xorg-server (Ubuntu) => xserver-xorg-video-intel
(Ubuntu)
