<pre>I tried with a BDW-U platform with same CPU, I'm not able to reproduce it.
Installing the graphic stack will probably solve your problem.
You can follow this guide to install last version of each drivers:
<a href="https://01.org/linuxgraphics/documentation/build-guide-0">https://01.org/linuxgraphics/documentation/build-guide-0</a>
Or install the last release:
<a href="https://01.org/linuxgraphics/downloads/2015q4-intel-graphics-stack-release">https://01.org/linuxgraphics/downloads/2015q4-intel-graphics-stack-release</a>
Or also use this installer:
<a href="https://01.org/linuxgraphics/downloads/intel-graphics-installer-linux-1.2.1">https://01.org/linuxgraphics/downloads/intel-graphics-installer-linux-1.2.1</a>
I decrease priority and severity until you confirm.
