Unity pixelating model

I’m using a low poly LOD of a tree as a separate model (12 triangles). Unity behaves strangely with it’s rendering changing back and forth it to a very pixelated version and back to normal without any patterns and at random times. Attached both images (1 is normal and 2 is pixelated)

The model does not have any LOD’s.

Might be using different mipmaps? But it shouldn’t be this extreme. Could you show the gameobjects in Unity?
