@DuarteFarrajotaRamos @kimholder Ah, to clarify, I am only seeing the problem in cycles

In the viewport all is well until the numbers get much more extreme (or the clipping frustum is made stupidly large)

If you get in close, you can see that it only resembles a geometry problem from a distance. In close there are clearly strange precision aliasing things happening:

(thats at 5000 units in +X)

I can see it at 1000, though it's much subtler

Also, the cycles artifacts don't really look like typical Z fighting artifacts

Which makes sense, as cycles works so differently from viewport rendering that it would be weird if they were the same..
