Short description of error
Glossy black material generates a lot of black pixels NaN in final render. The more render samples the more NaN pixels. In the viewport is less noticeable because their are less render samples. Turn off SSR and NaN pixels are gone.

See attach image:

Exact steps for others to reproduce the error
Load attach blender file "Glossy SSR_NAN_Bug.blend".

Render F12 notice all the black NAN pixels. Turn off SSR and all the black NaN pixels are gone.

Where did you see that these pixels are NaN instead of just black?

I can reproduce what I can see in the screenshot. I don't know if this is a bug or a mistake on your side.
@Clément Foucault (fclem) will know.

I don't know for sure if it is a NaN, but when I change the black color of all zeros to a red color the problem is fixed. I am using standard nodes that I are supported in Eevee and it works fine in Cycles.

I can confirm this issue, materials work in cycles but in eevee, at certain angles, I also get these black pixels.

I cannot reproduce anymore. Feel free to reopen if this is still happening on your setup.
