System Information
Operating system: macOS 11.2.3
Graphics card: AMD RX 5700 XT

Blender Version
Broken: 2.92 (downloaded from Steam)
Worked: I don't know

Short description of error
Viewport appears empty in Shading mode when I'm using my eGPU. With my Intel Iris iGPU, the Viewport Shading mode appears normal.

Exact steps for others to reproduce the error
Nebula.blend

Locate your Blender.app and right click it, choose "Get Info".
Make sure "Prefer External GPU" is deselected from the Blender.app info screen.
Load up Blender and the file I've attached. Turn on Shading Viewport.
You should see white particles. Good. Now close Blender.
Go back to the Blender.app info screen, now enable Prefer External GPU.
Do step 3. again, except this time you might notice that you see nothing in Viewport.
Congrats, you've now reproduced the bug (hopefully). I'm hoping this bug gets fixed soon as my iGPU is pretty much equal to a potato, so I have to use my eGPU so I could actually work with stuff.

I should probably note that this issue seems to only happen with that project, if I open a new project and go to Viewport Shading, the default cube does appear like expected.

I checked the daily builds and the latest one on Steam. The issue still persists.

Also, it appears you're using Windows 10. This seems to only happen on macOS, and possibly only on Navi 10 GPUs.

@Piipperi , can you reproduce with High Quality Normals enabled?: {nav Render Properties > Performance > High Quality Normals}

(This may not help)

Actually it's a long standing issue. see- #65873 (Eevee - no volume density textures when using Vega 64 external gpu on macOS Mojave)
Will close this as duplicate. Feel free to comment if there is misunderstanding. I will reopen the report in that case.
