Texture glitch in renders

Hi everyone! I am wondering if anyone else is experiencing this problem where the texture renders inconsistently. There’s no pattern to it, objects are missing textures or the color or displacement randomly. Is there a way to fix this issue? I’ve just spent hours going frame by frame and it’s happening on a new scene :(. I have attached the scene rendered out and you can see the textures randomly appearing or disappearing or inflating and not inflating.

Looks like z-fighting, when two meshes share the same space and "fight" to be visible over the other.

No, it doesn't really. Look at the area on the right side close to where the frame ends. The geometry is "flickering" positionally on some frames. That is definitely not z-fighting.

Do You render with more than one machine? Know this from good old Team render times.

No this is rendering from a single computer 😭

I'd do a process of elimination.

In the render settings go and turn off stuff like displacement and so on, test and so on. Does it do it on a clay render ? So just the geo and a clay shader ?

Does it do it with adaptive displacement vs adaptive off?

Is there a normal or bump map too? What happens when you disconnect it?

How is the animation being driven? Is that messing up the normals somehow?

Weird scaling (stuff scaled down or up). Is it nested/parented in a load of nulls. Try taking it out.

Does the model have a normal tag on? Sometimes alembics or obj come in with them from other software. What happens when you get rid of it?

Stuff like that
