Chrome's WebGPU support for the Imagination PowerVR GPU in the Pixel 10 family (Tensor G5) is still buggy — broken compute (e.g. the gsplat GPU radix sort) and shader miscompiles, with Dawn still carrying device-specific workarounds and CTS suppressions.
Changes:
WebgpuGraphicsDevice.createDevice()now fails (returns null, with a warning) when the adapter reports vendorimg-tec, socreateGraphicsDevice()falls back to WebGL2 automatically via its existing device-type chain. No app-side changes needed.Detection uses the standard
GPUAdapterInfoAPI; on Chrome for Android theimg-tecvendor currently only matches Tensor G5 devices, as older PowerVR parts were never allowlisted for WebGPU.Temporary workaround — tracked for removal in #8874.
