Ambient Occlusion Glitch

Hi there! I don’t have much hope for a resolution but I’d like to at least make a record of this glitching behaviour for Arctic Mode:


It’s not a problem with the geometry, which display perfectly when in isolation:

I’ve been noticing this lately with other polysurfaces with any curved edges.

I’d like to know could you share this 3dm file?

This could be duplicate objects, post the file as Jessesn asked if you aren’t sure.
