5.5 Nanite causing horrible white aliasing outline

I don’t know if anyone can replicate this because it’s very hard to see without using some sort of night vision post process, but it seems there’s an issue with 5.5 nanite which causes this extremely horrible aliasing outline.
Nanite on:


Nanite off:

I’ve tried a whole bunch of project settings and scalability settings, nothing affects it. Some meshes seem to have it worse than others: Right side wall has a lesser problem, clearly.

This wasn’t happening in 5.4. Any ideas?

I’ve tried basically everything I can think of. This problem showed itself as soon as I migrated my 5.4 project to 5.5, so I know I didn’t change anything.

I think it’s some kind of nanite anti-aliasing change/bug?
I’ve made a new project and swapped my content into it to test in a freshly installed 5.5 project. Same results.

Some meshes have it worse than others, but I’m not sure why. Maybe there’s more vertices on the edges so it’s more pronounced.

I’ve tried turning on/off a plethora of project settings.

Maybe there’s some console command that will fix it but that’s beyond my knowledge. Help?
