Bug with Fog Color + Affect Shadows + DR

There appears to be a bug with Fog Color + Affect Shadows +DR in 1.5rc2

With a fog color, and affect shadows turned on, single machine rendering:

And then when I turn on DR:

This scene is lit using a Vray Sun + Sky and the camera is a VRay Physical Camera with exposure turned on.

I’ve received off-color buckets with fog enabled and have sent Chaos information regarding that.

I have exactly the same problem as Dynedain when using DR. Is there any update regarding this as it’s proving a bit of a pain?

Does this problem still occur in vray 1.5 RC3? or has it been fixed

MAX 8, V-Ray 1.5 RC3
DR test - no problem with Fog color and Affect Shadow.
