Weird Flickering on Inclines, very prominent on mountains

I am getting these weird lines on mountains with Voxy. It's happening on all the shaders I have, and sometime even without shaders on. I've tried fiddling with the TAA settings, and Voxy LOD quality, and it seems the flickering in less with lower Voxy LOD quality, but it is still there.

I found an older post on reddit of someone having the same issue with vanilla render distances, something about "pixel conflicts" and they solved it by increasing the vanilla mipmapping. I tried that but it didn't work, my assumption being that the vanilla setting doesn't change Voxy LODS.

Please someone help me, this is driving me insane.

I recommend checking with just voxy and dependencies if it still happens no one wants to sort through a whole list of mods if one causes a slight issue

[Amiiban]

I tried with just voxy and dependencies too on 1.21.10, comparing the 0.2.9 build to the 0.2.6 build the ambient occlusion effect is a lot more unstable, installing vivecraft it's got a weird grid like look to it, following your head which looks incredibly strange, and with the simple zoom mod you can more clearly see big swathes of the terrain have ambient occlusion off in a wavy pattern. also noticeable in general is this perfect circle on the terrain where ambient occlusion does not render in all cardinal directions.

[Amiiban]

worth noting we both have nvidia gpus but I wasn't using shaders

[Kieslander]

I tested on the 1.21.11, with only Voxy, Sodium, and Iris installed. And got the same issue. Although I did notice it was less prominent, maybe cause it was just vanilla terrain instead of the modded terrain in the initial post.
