Good catch.

I looked at this in some detail and I'm pretty sure it's occurring because those pieces of geometry have weird normals. The abrupt transition of shading is occurring because that's where the normal is actually pointing backward away from the camera, so the shader is flipping it to point back at the camera.

In data R672 I changed the way I correct backward-pointing normals so that it reflects the normal back at the camera instead of flipping it. It's less correct for double sided surfaces, but it prevents the abrupt shading change for cases like this.
