Bug: Coplanar faces + VRayClipper = artifacts

[Laserschwert]

I've noticed that coplanar faces cause artifacts in rendering, even when clipped away by a VRayClipper. See the noisy area under the "archway"? That's exactly the part where the two objects have coplanar faces. Ideally if clipped away this shouldn't be there.

Does Secondary Rays Bias option helps here? If not maybe we have to think a way to resolve that with the Clipper.

Secondary Rays Bias doesn't help in my tests, it's still a good idea to test in into your environment however.

Yes, I tested it too, but it didn't help.

I thought secondary rays bias was only for faces that were JUST close together, but not 100% coplanar?
