Anyone else having this issue, appears to be z-fighting

Just reloaded the game thought I would check it out. When I get close to planets there seems to be a point that extends down fairly near to the surface where this happens. Once I get close enough to the surface it goes away and if I am far enough out it doesn't seem to show or just isn't visible. What it looks like is the planet core keeps toggling size and then settles once you are close enough.
