I am having trouble running the examples/hello-triangle sample using the instructions at:

I have tried running under Firefox & Safari for webgpu. I have tried running under Chrome & Firefox for webgl.

WebGPU errors

In Firefox 85.0.2 I get:

panicked at 'Failed to find an appropriate adapter', examples/hello-triangle/main.rs:19:10

In summary, I haven't got the triangles example to run in any web browser.

Any help would be appreciated. Thank you!

You don't get WebGPU in FF stable, it's too early. See https://github.com/gpuweb/gpuweb/wiki/Implementation-Status#firefox for how to get it enabled.

Firefox Nightly 87.0a1 (2021-02-11) macOS Big Sur

dom.webgpu.enabled = true
gfx.webrender.all = true
Restart browser
WebGPU version of index.html

Result: Completely black canvas + console message:

I can confirm this. Something got broken, will investigate.

Thank you! ❤️

Answer 5 · 2021-02-24T21:47:56.000Z

@bes I believe this should work now. The issue was in Gecko, unrelated to WebGPU.
