Baked Directional Specular GI creates seams

Questions & Answers

I’ve noticed that in Unity 5 baked directional specular GI creates seams like in this image:

In certain situations it even creates the same effect on the borders of geometry.

The scene is basically two cubes with the same size positioned using surface snapping. The seam appears ONLY with baked lighting in Directional Specular mode. Changing the mode to only Direcitonal fixes it. Is this a bug or is it possible to avoid it?

Looks like it might be a bug if it’s the same problem as in this thread: Unity 5 light problem
