Even so, the original report makes no mention of using nightly or a very recent kernel. Also, the link to github implies the problem started to happen after an upgrade from Ubuntu 14.04 to 14.10. The latter uses kernel 3.16 and xf86-video-intel version 2.99.914. I am able to reproduce the bug with that config, getting the screen divided horizontally like in the attached screenshot.

Adding

   Option "Present" "false"

to the device section of xorg.conf works around the problem.
