Bug#704178: Acknowledgement (xserver-xorg-video-intel: [Ivybridge] "Overlay" window causing colour cast appears during video playback)

[Mike Brodbelt <mike@coruscant.org.uk>]

Some further information on this bug. It turns out that it does not only 
appear during video playback, but also happens for windows that are 
animating, or moving large amounts of graphics data in other ways.

For example, the "coverflow" area of a Calibre window can demonstrate 
the behaviour, as can a browser window which is rapidly moving (i.e. 
Google Street View, when moving around).
