Bug

Not sure if this might be fixed already by recent commits, but I guess this is something for @Clément Foucault (fclem) to look at?

@Oscar Orlando Caballero Moreno (oocaballerom) Is the problem happening with other HDRIs? does it happen in lookdev mode?

@Clément Foucault (fclem) Yes, This is happening with all hdri's, the only differences is that some of them produce dark glitches. All in Lookdev Mode.

I've been comparing Windows and Mac OSX versions and I found Roughness is not working the same, In Mac OSX Roughness seems to displace the reflections.

This examples are with the last build Oct 31 2018 00:28:22 for Mac OSX

I want to know if you are seeing the videos I'm submitting. It seems like they are broken so If you can't see it please tell me and I will add them to another source first.

Videos are working in firefox for me.

The roughness displacement thing is a feature to better fit real specular reflections.

That said it seems there is problems with mipmap prefiltering on your gpu too.

Do you have issues with Ambient Occlusion, SSR?

@Clément Foucault (fclem) Ambient Occlusion and SSR are looking fantastic.

I'll be here trying all versions and notifying you whenever the bug is fixed. Thank you so much.

If you need some other information, please let me know.
