No, I believe that would be a bug. Do you have a scene for it?

Would this be the reason why I get vastly different FG computation on 
separate rendertiles seen through transparent refractive and reflective 
surfaces, even though they are rendered on the same machine?

What would then be the method for leaving transparent refractive and 
reflective boxes out of FG calculations for stuff inside the boxes on which 
I need FG?
