    Yes but I have yet to draw the connection to my change.
    Also I cannot seem to replicate these failures.

    From logs it fails [here](https://source.chromium.org/chromium/chromium/src/+/main:third_party/angle/third_party/dawn/src/dawn/native/vulkan/PhysicalDeviceVk.cpp;drc=a5a289f9476fa269f837d7daef8bb12af6e464ca;l=239) and then crashes [here](https://source.chromium.org/chromium/chromium/src/+/main:gpu/command_buffer/tests/webgpu_mailbox_unittest.cc;drc=cad5903484d19fe15c828ee76c0a507ddc42184e;l=1492) because adapter is null.

    Peter McNeeley

    Yes but I have yet to draw the connection to my change.
    Also I cannot seem to replicate these failures.

    Vasiliy Telezhnikov

    The only change that might have effect is in `gpu/command_buffer/service/webgpu_decoder_impl.cc`, rest doesn't run in crashing tests.

    I guess it now fails to create adapter if we don't have `SharedFenceSyncFD`, which we probably don't on VM?

    Peter McNeeley

    Right this was the original path I was thinking. But the log you mentioned also seems critical. I also noticed a change in vulkan-deps. Is it possible that that cause a change which results in that early log failure?

    Since this is all 'vm' I should be able to repo locally on my cloudtop.
    I also in all honesty dont know why the SyncFD wouldnt work even if virtualized.

    The log is present in a passing run too:
    ```
    Warning: Vulkan shaderUniform*ArrayDynamicIndexing required.
    - While initializing adapter (backend=BackendType::Vulkan)
    at InitializeImpl (third_party/dawn/src/dawn/native/vulkan/PhysicalDeviceVk.cpp:240)

    gpu/command_buffer/tests/webgpu_mailbox_unittest.cc:1494: Skipped
    info.backendType != wgpu::BackendType::D3D12
    ```

    But it is able to get adapter (maybe GL compat?) and skip the test, as the test is windows only anyway.
