Hey guys, I'm rendering some foliage which are instanced and done using instancefile.
My PC specs are :
Intel(R) Core(TM) i9-14900K
32GB ram
16GB RTX 4070super

The render settings are at default except automatic sampling, random noise patterns are off, progressive passes are 128 and bucket size is 256. And also no hybrid rendering.

This glitch flickers and moves around in the frame. Ive searched everywhere online and theres nothing about this issue.
