Hello. When putting Roughness to 0 on a Metallic Material Setting (Using a Metallic map here, so it's set to 0 or 1) for Principled Shader in Blender 2.8 on MACOS  10.14.5 using a Vega 64 AMD as external EGPU the material gets white. Using Blender 2.8 latest built from june and also latest built of RPR. See Pictures below for Reference.

 

Roughness at .001   Roughness at 0

This doesnt happen in Cycles, and therefor can be a bit of a pain when switching between the two. Anybody else experiencing this? Hope i could save someone else some time.
