UHDC flicker

[FrostKiwi]

As submited by Ondra's request: https://forum.corona-renderer.com/index.php/topic,6581.msg#msg45186
I'd like to add, that I rerendered the scene with the newest build (21.01.15) and although you have implemented a flicker free and fast precomp it still flickers.
Again, whole short sequence rendered with one (animation flicker free option), precalculated UHDC 200k bounces file from the corner of the room. HD cache sucess was always around 80%.
1080p, 8passes, 24 gi, 4 light multiplyer, 4 max ray.
Heavy flickering around half of the vid.
