<pre>Running linus master of today (also reproduced on 3.13), with this hardware:
00:02.0 VGA compatible controller [0300]: Intel Corporation ValleyView Gen7
[8086:0f31] (rev 0e)
Inside a Bay Trail M N2807
Choosing any of the 3 interlaced resolutions supported by my display results in
a "wobbly" output. It is as if on every update, even for static images, each
horizontal row of pixels gets jolted up/down/up/down.
I captured a video, the camera compensated a lot, it feels a lot worse than it
looks here, but to give you an idea:

Please let me know how I can help with diagnosis/debug.</pre>
