Additional Notes

It appears that these weird lines are perfectly lined up with the grid preview

Ive noticed this after v35.0.0 update aswell. Sometimes happens, sometimes doesnt.

I think your idea may be correct

Close to you is loaded landscape, past that line would be unloaded landscape, they are out of sync.
I don’t know if landscape has its own HLOD thing going on seperate to build HLODs, I did assume so because landscapes always seen on a map with no HLODs built
I wonder if build HLODs does anything to it

Maybe related to your landscape collision issues ???

it might be… I haven’t built the HLODs so maybe when I do it might fix the issue
