I think you need to check your topology.. you've got overlapping faces.. That's how that looks like.. has nothing to do with this (fixed) bug as I see it

Hi!
I use Radeon Vega 64
I have some other type of overlapping glitches in viewport when using bevel modifier in Edit Mode.
It randomly flickers and changing during viewport movements.

Thats unfortunate for us Mac users... I guess there is not much of a chance that we will see Metal support in the future - maybe through the help of MoltenVK?

@Hans-Simon Sagave (wizardx) I read that there are plans for a Metal wrapper for Vulkan in the future. I guess a pure Metal version of Blender would require maintaining a separate macOS branch. But if you already want a taste of Metal-assisted rendering, you can try Radeon ProRender. It's quite well-integrated in Blender and is also free.

Cycles: OpenCL on macOS has been disabled

There was a growing payload of bugs in Cycles related on OpenCL on macOS
platform, and those issues were caused by a compiler bug, which we have no
control over.

Surely, it is sometimes possible to work compiler bugs around from a
source, but we are facing some of the issues which are not solvable in this
way. Also, such solutions are usually short-living,. since adding more
features are often kicking compiler to provide buggy binary again.

In this case compiler will not get fixed since Apple decided to discontinue
OpenCL on its platform.

So the decision was made to drop support of OpenCL, keep official features
of Blender stable and predictable, and focus on things we have control over.

P.S. Older Blender releases are always available. Surely, this sounds like
using an ancient software without neat features. But we can't push Cycles
OpenCL on macOS measurably beyond that anyway.

Hans-Simon Sagave (wizardx) added a comment to T52145: Denoising feature. Bug on GPU render (Mac OsX 10.11.6).

Apple will not longer develop OpenCL... So what about Metal? This is the new one. It's much much faster on Mac and is the new language! Will Blender ever support Metal? This'd be a great idea: much faster render times on Mac, denoising and baking would work as well. Can we expect something like this for 2.81??? It would bring up Blender for a new level on Mac!

Yeah it would totally be great if this could be fixed! I tried it with 2.8 and 2.79b without success,.. With 2.8 I get the random black tiles. I just tried it again with 2.79b but that made my Mac reboot itself:( Tried it again just to be sure but the second time my whole screen went yellow and I had to unplug my eGPU.
Using a MacBook Pro 2018 i9 32GB ram with AMD Vega56 eGPU running MacOS Mojave.
Really hoping this can get fixed soon. In the meantime, does anyone know a way to still use the denoise function?

This is not an error only a warning. As long as shader interface (in and out variables) matches the compilation / linking is ok.
We had to make sure the interface matches for eevee in the past so that's why there is many related warning.

Keep in mind that you don't need cuda and also that for the make command to work you need to put cmake in your PATH (export PATH=$PATH:/path/to/cmake/bin/in/his/content/folder) If you need futher assistance go to blendercoders on freenode I'm sure they will be people to help you and I might be here as well as Abrases

Pawel on my end it's doesn't make any difference but you have faster and different hardware. I recorded a small video of the demonstration with and without the debug menu, it's difficult to see with the lag that it create but even without the record I don't see any difference.

I can confirm that enabling the debug menu to 23 does smooth the fps and running a more complex scene doesn't seems to slow down more the viewport. I'm available for further debugging.
