[Help] Unity 2018 flickering edge in build only

Hi guys,
today I've updated from Unity 2017 to Unity 2018.3.6 and now I have an odd error I can't figure out how to solve.

If I play the scene from editor everything looks good, exactly as in 2017 version, if I prepare a build and play it some materials show very flickering edges, most of them seems to use Standard or Standard specular shader.

Gif have not a very high quality so it's not evident as I see it, but it's quite evident looking at the metallic shelf in the back

Hope someone can help me cause I've tried make it work the whole day with no success.

Thanks,
Gabriele
