Thanks

Interesting. Can you send us any scene where this happens? https://coronarenderer.freshdesk.com/support/tickets/new

The problem is related to GI/AA, when its value is different from 16

Actually it was because AO map was used in material override slot, and it behaves slightly different depending on the GIvsAA value. Interactive rendering uses GIvsAA / 4 (AFAIK), and hence the difference. I will create a bug report based on this, as maybe it would be possible to make AO result consistent regardless of GIvsAA settings.
