Vray Light Select Flickering

Animation for the Light Select element flickers. Rendering BF/LC (light cache samples - 2000)

The scene is a camera flying around the exterior of a building.
There’s a Light Select element with all of the interior lights (multiplier turned up to 20).

Is this a bug or a limitation of adaptive lights?

Sorry for the late reply on this; can you get me the scene to vlado@chaosgroup.com ? I have a potential fix that I want to test.

Best regards,
