No, I don't have zero edges in Vue. If my terrain is made in GC2, I always zero-edge there, as I have more control there. In Vue, there's only one button to zero-edge and that's it, whereas in GC2 you can specify some more settings.

Would zero-edge in GC2 also remove the artifacts? I don't know. I very rarely use non-zero-edged terrains, my experience is limited there.
