Environment Texture Bug.blend
Metallic and Specular Materials got noise and grit when using environment textures. I try in another mac and it seems ok, but not in this one
I add my specifications and a video to show whats happening.

Not sure if this might be fixed already by recent commits, but I guess this is something for @fclem to look at?
@OscarOrlandoCaballeroMoreno Is the problem happening with other HDRIs? does it happen in lookdev mode?
@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?
@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.
@fclem I installed Blender 2.80 Beta macOS 64 bit
November 30, 00:05:31 -
63c0653170The glitches are not fixed, it still looks as in preview versions.
This are Flat and Smooth Shading Screenshots.
Can you show me spheres with different roughness?
@fclem This is the comparison of two computers.
The Mac OSX showing the glitches.

The behaviour of the roughness value has been the same since I reported this bug.
I've added a new option to test gpu driver workarounds :
--debug-gpu-force-workaroundsit should be in the next build (see if the build is from the 5th dec).
Launch blender using this option to see if that changes anything.
@fclem There's no a build since 4th dec for Mac OSX.
@fclem How can I use the option "--debug-gpu-force-workarounds"?

Is this still an issue in the latest builds?
If it is, here's some info on running Blender from the command line:
https://docs.blender.org/manual/en/dev/render/workflows/command_line.html?highlight=command%20line#macos
You would run
Changed status from 'Open' to: 'Archived'
Assuming this is fixed unless anyone can confirm it's still a bug.
@brecht @fclem I'm sorry, I'm not able to test if this bug is fixed or recreate it, sometime ago I decided to upgrade from Sierra to High Sierra because of this issue and the problem was gone after that.
Ok, good to hear.
