strange visual artefacts on moons

[TimKerbin]

I don't know if this is directly related to KSP graphics settings, or being caused by a  specific mod, for example Scatterer 1.1.1. If I rotate the camera the visual artefacts go away, but if I rotate the camera back, they return. I've so far noticed it on the surfaces of Minmus and the Mun. I don't think I've seen it on the surface of Kerbin yet.

They look like shadowing artefacts. In fact it's just occurred to me to turn off 'Terrain shadows' in the Scatterer options and see if that helps.

Do you have AntiAliasing turned off? It looks like maybe that plus a mod (Scatterer is a great guess) together to me, though I don't use either.

Have you tried running the game without Scatterer installed? That would tell you right away if that was the culprit.
