GI Flickering in animation

[dfcorona]

I wanted to see what everyone thought before I decide if this is something I should send to Chaos as a bug of some sorts. I use primarily 4k for secondary like I did a long time ago, but now I get Flickering in GI on a lot of scenes. Back in the day I switched from UHD to 4K because I was getting much faster calculations and better quality. I never got flickering from 4K before. I tried same scenes with UHD, and am getting much less flickering but still on some scenes still getting really bad flickering. Working on really big scenes now and in the past I can confidently say this was really never an issue before. Seems like with the newest Corona I'm having a lot of GI flickering issues, am I the only one?

Corona 12 Update 1
Max 2025.3
Tried 4k & UHD
Set to Animation (flicker-free)

Hi, could you please contact us here and attach the problematic scene archived with all assets? https://support.chaos.com/hc/en-us/requests/new
Thanks!

UHD Cache in "animation" preset definitely shouldn't flicker.
The 4K Cache is still experimental, so there may be some minor issues with it. Perhaps we can fix it though. :)

Okay, I'll get the scene together. It's quite large!
