OpenGL mesh intersection disturbance

Question

I have this weird issue in my program where the intersection between to meshes gets really messed up the further away I go. What is this phenomenon called and how do I fix it.

Here is a picture of it

Answer 1

It is called Z-fighting. Use higher-res depth buffer.

But it could also mean that your mesh(es) has co-planar faces; you'd fix that by offsetting affected faces by a little.
