Bug Reflection probe bakes refractive materials with stripe artifacts

Hi,

I'm encountering that reflection probes bakes transparent refractive materials with some wrong grey stripes onto the surface. They clearly come from the Lit Shader with turned on Refraction. If I disable the Refraction in the Shader, the stripes are gone during rebake. But then I loose the refraction as well ...

 

Bump, is this a bug or just a limition of baked probes with refraction inside the scene? I really don't know ...
