Found that this phenomena is related to terrain draw distance, specifically extremes on the low end. When joining an MP server with different settings, the terrain draw distance will use those settings, but will not reset to prior user specifications. Temporary fix is to just reset these each and every time to default, or whatever your preferred specifications are. Having the ability to save a "preset" that automatically reverts between game sessions might be a nice patch.
Resetting them to default seems to have fixed this particular issue as a whole. Again, not sure why they are radically different based on the platform being used with the same settings applied. 🤷♂️
