HDR demo not working when I have WebGPU flag enabled on chrome

[shanebenlolo]

Hello,

Thank you for these tutorials. I am trying to checkout the demo for the HDR example found here: https://sotrh.github.io/learn-wgpu/intermediate/tutorial13-hdr/#demo

I am receiving the following error when the demo loads:

panicked at code/intermediate/tutorial13-hdr/src/lib.rs:269:14:
called `Option::unwrap()` on a `None` value

which corresponds to this code block in the example code:

        let adapter = instance
            .request_adapter(&wgpu::RequestAdapterOptions {
                power_preference: wgpu::PowerPreference::default(),
                compatible_surface: Some(&surface),
                force_fallback_adapter: false,
            })
            .await
            .unwrap();

As you can see from the image above, I have WebGPU enabled in my settings and have reset chrome.

I am also able to run this WebGPU testing website with no issues: https://toji.github.io/webgpu-test/

only half of these work on my machine as well. For instance, the Triangle and Compute Shader Blur examples both work, but the Sphere (Babylon.js) does not. So it is probably just a system-specific issue. If anyone else has had this issue please let me know if / how you managed to resolve it.

I also see the same problem for Chrome 119 version. Is it a wgpu issue?

I think it's fair to assume this is not a wgpu issue as it is not onfined to only projects written using wgpu, closing now thank you for verifying you are having issues with the demos as well.
