Hi Brecht, thanks so much for the suggestion, the problem seems to be that my normals in particular cases were flipped. I can reproduce it in blender by manually flipping the normals. Please close this for now and I will re-open if I have further problems.

I have been unable to reproduce this in the current version of blender yet. Was there any updates to the principled shader between 1.79 and 1.79.1?

OK I will try to reproduce this problem in Blender. Currently I am experiencing it when using the cycles API directly.

Example on water surface using Principled BSDF as a volumetric shader. IOR is set to 1.33 and Specular to 0.5
