Z-Fighting Issue on Down-Facing Surfaces

I only just got back from a vacation, so this was my first chance to give the new update a go. While the majority of it seems to be working well, there is a small problem: any flat, down-ward facing mesh surface seems to be suffering from some effect that looks a bit like z-fighting.



I've checked the meshes, they only have one properly-UV'd face there. And a handful of assets in the default maps seem to be suffering from the same. I can't be sure of every spot, but the undersides of the streetlights and transformers in ECU's town are one example.

If nobody else has this issue, I'll consider a fresh reinstall. Otherwise, I'd rather avoid that if possible (limited internet).

 

This issue is also happening on my end, so a fresh reinstall will probably not fix it.

I have the same issue

 

yes me to, I thought it was something I had done wrong, but since many more have it, then it certainly after the Update, but I`m sure It will be worked out
