Glitchy display, visible wireframe behind polygon face

[Anonymous]

As you can see in the attached photo, up close there is no problem, in shaded mode and as it should I can't see the edge that is behind the face. However when I zoom out at a certain point the edge that is supposed to be behind the face starts to become visible. Why is this happening?

I am on a NVIDIA Titan XP, latest drivers 24.21.13.9811, Maya 2018

NOTE: I am running the Titan XP through a Razer Core V2 (external enclosure for laptop), I highly doubt this has anything to do with it though

that (seems to be)  Z(-Buffer) fighting.

It usually happens when your camera frustum has a too broad range (say 0.001 to 100000) (keyword: floating-point precision errors)

If you do large-scale stuff like landscapes and such it is usually better to raise your min. frustum to something more reasonable (say 1.0 or more, when I do stuff in realworld scale I usually go up to 10 meters for the frustum minimum,.. thats 1000) sure at those ranges you get clipping if you have to go up-close to some verts.. but then your detail handling might be wrong ...or swap the frustum.. you can make shelf-buttons to accommodate for a few cases (close,mid,range)

sometimes  it is also not recommended to work in realworld scales as mesh-binding/skinning will create weird results if you move your entity too far away from the world-origin, the geometry literally gets distorted.
