1873496 - WebGPU CTS test cases' init. of D3D12 occasionally fail with `DXGI_ERROR_INVALID_CALL` in CI

Status: NEW

(Core :: Graphics: WebGPU, defect, P2)

Description

[Erich Gubler [:ErichDonGubler]]

For some reason, attempts to initialize WebGPU adapters against the D3D12 backend occasionally run into an issue where a DXGI_ERROR_INVALID_CALL (hex. value 0x887A0001) is returned from Windows APIs. The cause is unclear; we are uncertain if this is environmental, or something that needs to be improved with all usage of D3D12 in WGPU. Impact is well-understood: this causes arbitrary WebGPU CTS tests to fail in large swaths.

This can be observed in jobs like this one: https://treeherder.mozilla.org/logviewer?job_id=441762378&repo=try&lineNumber=22331-22366

WebGPU is unreleased tech. Dropping Severity to S3 to remove from org tracking.

I'm not currently working on this; dropping assignment to indicate such.
