This is a weird thing, and I think it happened when I started adding mods to Kerbal Space Program. I have no Idea, but my assumption is the mods that are causing the problem.
So here's an image of it, starting from just about 4 kms away:

(Just ignore why is it on a Gemoo app I tried to get an image from the URL but this website got my questions incorrectly.)
But then more than 13kms away, this will happen (same camera in place):

It won't take someone with a few days of experience in KSP to tell something is wrong:

The reason is why? I think it might be because of the mods, but I don't want to sacrifice my mods for the render "bug" to disappear.
Let me know if you cannot open the links.
I will check back in this forum in about 12 hours or more because I am swamped at the time.
