The failure occurs at test time, solely on linux platforms.

wgpu/utils/device.py:15: in get_default_device
adapter = wgpu.gpu.request_adapter_sync(power_preference="high-performance")
>           raise RuntimeError(error)
E           RuntimeError: Request adapter failed (1): Validation Error
E           
E           Caused by:
E             No suitable adapter found

Could someone with a real linux machine build the package successfully? Just to demonstrate if this is an emulation issue?
Upon having successfully built the package, you should be able to produce the attached image by running the wgpu-py/examples/triangle.py example.

I used the following dev-shell:

pkgs.mkShellNoCC {
  packages = with pkgs; [
    (python3.withPackages (
      p: [ p.wgpu-py ] ++ p.wgpu-py.optional-dependencies.glfw
    ))
  ];
}

Addendum: it appears ofborgs's passthru.tests on x86_64-darwin has failed for a similar reason, despite passing locally on my darwin system.

I've also built and validated the docs now.
All tests apart from version are executed exclusively on Darwin due to what I assume are sandboxing issues on Linux. I'd be very grateful if a reviewer could use the built package and run wgpu-py's examples/triangle.py example on a Linux machine, i.e. outside of a sandbox.

Their GitHub workflow references llvmpipe (i.e. mesa.llvmpipeHook) but that doesn't seem to help.
