I was a little hasty with the 'send' button before because I wanted to 
mention I didn't think you'd want such variance between 3.7.0 and 3.7.1

It's the Jade pigment in textures.inc.  I also noticed it with 
Apocolypse.
Oddly, I also use Blood_Marble and Blue_Sky3 and those seem fine.

I'm gonna go out on a limb and say this scene gives different results 
for all versions of 3.7.0 vs. 3.7.1.
