Nothing strange about that; as you lower the glossiness and the blurrier or stronger the frost effect gets, the less definition that V-ray has to calculate for the objects behind the glass. And vice versa with the reverse; as you increase the value, the 'clearer' the object becomes and the more definition or resolution that has to be calculated while still factoring in the glossy refractive or subsurface scattering effect.
