This is called Z-fighting, it occurs when two surfaces are at the same or almost the same position and the renderer can’t decide what’s under what.
Z-fighting, also called stitching or planefighting, is a phenomenon in 3D rendering that occurs when two or more primitives have very similar distances to the camera. This would cause them to have near-similar or identical values in the z-buffer, which keeps track of depth. This then means that when a specific pixel is being rendered, it is ambiguous which one of the two primitives are drawn in that pixel because the z-buffer cannot distinguish precisely which one is farther from the other.

If you move away from something then it can also happen if surfaces are close–the depth of the view changes over distance so surfaces that are technically not in the same space will end up in the same depth when they’re further away and get the same Z-fighting effect.
