<span class="quote">> (There is certainly a kernel regression due to planes)</span >
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.</pre>
