<pre>Moving from <a href="https://bugzilla.kernel.org/show_bug.cgi?id=89251">https://bugzilla.kernel.org/show_bug.cgi?id=89251</a>
I have a small panel PC with Intel BayTrail-M chipset. Once the i915 driver is
loaded, the display (internally connected via eDP) shows every second pixel
line shifted one pixel to the right, which leads to "fuzzy" graphics. Booting
with "nomodeset" avoids the problem (see attachment). I tested with 3.16, 3.17
and 3.18 (problem persists).

Problem persists with 4.2.5, unfortunately.</pre>
