Web demo gallery crashing on Chrome (Linux)

[sgon00]

I noticed that the "Try the web demo gallery" is currently not working as expected. When running it in a browser, the app displays the following error: The app has crashed. See the developer console for details.

Environment:

• OS: Ubuntu 24.04.4 LTS
• Browser: Chrome Version 146.0.7680.164 (Official Build) (64-bit)

Console output:

panicked at demo/src/main.rs:57:21:
Failed to start eframe: JsValue("No suitable graphics adapter found; noop not requested, vulkan support not compiled in, metal support not compiled in, dx12 support not compiled in, gl support not compiled in, webgpu not requested")

chrome://gpu/ output:

While the demo works with vulkan enabled, this isn't a viable workaround as vulkan is experimental, breaks all video playback, and causes other issues.

I found the same issue on Chromium. On Firefox it says:

It seems to work for me on chrome Version 148.0.7778.178 (Official Build) (64-bit) running on Fedora.

However it is not working on firefox 149.0.2 (64-bit) with the exact same error message as @asceenl wrote
