Bug description:
[Impact]
running mplayer or vlc the video output is incorrect. There are are 2 line
steps on edges.
The problems is known and there is already an upstream fix available.
http://www.spinics.net/lists/intel-gfx/msg65030.html
I have rebuild the driver with git from 2015-04-28, and the video
output is correct now.
The bugfix is for Generation 8 Intel graphics like Intel NUC with Core
I5-5250 and HD6000 grahics in my case.
The used version is Ubuntu vivid amd64.
[Test Case]
Launch Skype, VLC or mplayer and use xv as video output.
A sample of the corruption can be found here:

[Regression Potential]
None. Admittedly I may not be the right one to fully assess the risk.
Any help on this matter would be much appreciated.
[Other Info]
Already fixed upstream.
