--- Comment #2 from Rodrigo Vivi <rodrigo.vivi at gmail.com> ---
Reported twice on HSW but I also see on BDW when alternating to fbcon and back
to X. I believe there is an error in the enable/disable enable/old logic
somewhere but I couldn't find. If this is the case it should affect many other
platforms not just BDW and HSW.

Another theory is something wrong with WM size as pointed out on dup of this.
