The fact that snapping doesn't work in this case makes sense, really, as the projected texel-size can change from frame to frame as the camera moves. It also explains why TAA helps mitigate this. Sorry for taking so long, I myself would like to have more time for this :D

@nicebyte.bsky.social I'm sad to report that snapping doesn't work, but overall it's not too bad as you can see. The swimming starts once the camera starts moving rather slow, but then TAA can clean this up. If you don't want TAA, then maybe you can have "TAA" on the cascade splits themselves
