Excessive noise with Adaptive Lights, Consistent Lighting Elements and VrScans

Hey, I have a scene here which causes excessive noise in the reflection element of a render. It is not visible in the RGB, only in the reflecion. When I disable Adaptive Domelight, it is gone. Also, when I render with override material and only leave the metal parts as is, it is gone as well.

Can anyboy confirm that this is an issue?
