Comment # 12 on bug 1206683 from Markus Ko���mann

My idea was that the common denominator for the problem is intel IGP in some
version.From 6th gen up to at least 8th gen. Dave Platers 4th gen Intel IGP 
doesn't seem to be affected
But that theory fails if intel IGP is completely disabled on your second system
and you don't use something like PRIME Render Offload
