Oliver Hookins (ohookins) added a comment to T49387: Blender 2.77 & up, GLSL Viewport rendering not working correctly, material glitches & artifacts.

I believe that I might also be suffering from this bug.

Jörn PM (ionflux) added a comment to T51604: Mesh/Edit-Mesh Auto-Smooth Split Normal Support.

It still doesn't seem to work with the edge split modifier. Compare renderings in Cacles vs. Eevee with smooth faces, sharp edges + edge split modifier (using blender2.8 / be4ebb7fa6c).

After looking through now with proper time, seems indeed some High Sierra issue.

Brecht Van Lommel (brecht) triaged T53945: Blender crash after enabling GPU render on Mac. Need to restart computer before Blender can be used again as Normal priority.

From the description, this must be a bug in the Apple OpenCL driver. We've seen this before where if it's given a complex OpenCL kernel, it can hang for a longe time and eventually crash or return an error.

So I'll open this again, yet I can't repro.
Factory startup is just that, it removes all settings to default, and removes GPU compute selection from settings.
Check if this happens with 2.79a-rc:
Blender 2.79a rc macOS

As it seems that it's not blender bug, marking this as resolved. Feel free to comment, I'll try to help.

Start with --factory-startup, then do some settings you usually have, and save it as new startup.blend

Which means,
When switching to factory settings, enabling Cycles and then switch to GPU and start a render, it actually works!

If you start with --factory-startup, does the kernel compiling hang?

Brecht Van Lommel (brecht) raised the priority of T53781: Dual Gpu's causing Blender Crash when opening User Prefs window from Incomplete to Normal.

This must be some issue with opening new windows when using multiple GPUs. I don't have a similar system setup to test this though, hopefully another developer can reproduce it..

alekulyn reopened T48880: "Failed to build shader variant" error on open-source amd drivers. as "Open".

I'm getting the same error on a AMD 5800K APU, which has the Radeon HD 7660D GPU, on startup in 2.8. The default cube displays, but its shader is just a bunch of random noise. I should mention that this only occurs with Eevee, and not any of the other render engines.

alekulyn added a comment to T51576: Blender crash when change to edit mode with Intel GPU.

Getting the same issue here on Linux with an AMD 5800K APU. Apparently, gpu_basic_shader is returning a null pointer which gets passed to GPU_shader_get_uniform, which then tries to point/access elements in that structure, resulting in a segfault.

Sergey Sharybin (sergey) closed T53468: Material viewport shading mode doesn't respect the "clip" image texture setting as Archived.

Thanks for the report, but this is a known limitation since initial Clipping implementation in Cycles: for GLSL e really need to use OpenGL clipping, which is fast but which would requite some internal changes in how we work with OpenGL textures. Currently, we only use one OpenGL texture per image, which will cause unpredictable results if the same image is used with different clipping/extension methods.

Its highly likely that this bug is specific to your hardware/driver configuration. These kinds of display issues are often caused by OpenGL driver bugs.

Sorry, but I have to reinstall Linux and resolve this problem, because the cause is the crashes in linux caused by inflated software that i dont support any more, and the single-core prosessor is more insufficient for editing armatures in blender
