I just checked the issue description as well as other contributions in there, it is another issue. I have experienced that too, and added my own comment + video.
Furthermore, I have created the issue for this specific problem:

Personally I believe it's an LOD problem, when you place a settlement / planetary station, you alter the regular terrain generation, that might work in most cases, but it seems to be some sort of conflict at close (higher details) LOD levels. Just my opinion.
