Eevee - no volume density textures when using Vega 64 external gpu on macOS Mojave
Open, NormalPublic

Description

System Information
Operating system: Darwin-18.6.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon RX Vega 64 OpenGL Engine ATI Technologies Inc. 4.1 ATI-2.9.26

Blender Version
Broken: version: 2.80 (sub 74), branch: blender2.7, commit date: 2019-06-16 23:08, hash: rB12da679fa094
Worked: Was working briefly with some builds in March 2019.

Short description of error
MacOS Mojave external GPU fails to render volumetric on Eevee if there is a density texture. Internal GPU works fine.

Exact steps for others to reproduce the error
Using external Vega 64:
On default cube, add principled volume shader to volume material output: volume looks correct.
Plug noise texture node into density input of principled volume shader: volume disappears.
Using internal Radeon 560x:
Exact same steps gives properly textured volume.

[Based on the default startup or an attached .blend file (as simple as possible)]
