Noise w/Blender Internal using 2 Scenes

Here is my very basic Blend file.

When I render normally, looks great…when I render 2 Scenes highlighted, I get tons of noise!


once I check an additional scene (my shadow pass), there is tons of noise!!!


Here is my blend file:
cube_shadow.blend (529 KB)

That is because your are rendering two cubes on top of one another.

OH CRAP!!! *facepalm
Thank you!
