Subject: [PATCH] Fix SV-2179: Wireframe - Rendering. Works only when
 Adv.light.model is disabled.

(Don't toggle ALM while in wireframe, bad things will happen...
or do, who am I to tell you how to live your life?
It'll look pretty cool actually, to fix that noise just toggle Wireframe once or twice.)
