Fixing Intel Graphics Glitching (Docky/Plank/Tint2) in Openbox on Samsung Ativ Book 8

I had a fairly subtle glitching issue on my Samsung Ativ Book 8 running Openbox on Debian Jessie. Basically icons in Docky/Plank had a orange box outline and Tint2 icons also looked unsmooth.

In order to fix I did the following:

cd /etc/X11/xorg.conf.d/
sudo nano 20-intel.conf

Then put the following in the file:

Section "Device"

Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
