Previously on MacOS, experimental WebGPU support already covered a lot of usecases. However, with the recent update it seems to have regressed: At startup of my application I get now `InvalidStateError: GPUCommandEncoder.finish: Unable to finish.` https://rerun.io/viewer/version/0.25.0?renderer=webgpu Much more basic, the rotating cube example doesn't work either, failing a bit differently with a device loss. https://webgpu.github.io/webgpu-samples/?sample=rotatingCube Simple triangle still works though: https://webgpu.github.io/webgpu-samples/?sample=helloTriangle Safari 26 @ MacOS 26 works fine in all these scenarios, but there's no easy way to detect this.

Not exactly the same as bug 299237, but the developer response there covers both. *** This bug has been marked as a duplicate of bug 299237 ***
