Weird compute shader behavior on apple silicon.

Bevy version

0.15

Relevant system information

My mac is an M1 mac from 2021

`AdapterInfo { name: "Apple M1 Pro", backend: Metal}`

What you did

I am making a multiplayer game with marching cubes, I had already tried with my windows desktop and my linux laptop, but when I tried with my mac it just didn't work properly.

What went wrong

This is the minimal reproduction on my desktop:

and here on my M1:

There is something that was messed up somewhere near the compute shader part.

Here is the minimal reproduction.

I'm sorry if I did this the wrong way, I don't usually do issues but this is blocking my development.

Probably needs reporting to wgpu. If there are no errors in the console, and it works fine on one platform but not the other (excluding things like supported GPU features causing a different codepath), then it's a bug in drivers/wgpu and should be handled by wgpu.

[Sigma-dev]

@JMS55 There are no errors/warnings in the console. I don't know if webgpu would appreciate my bevy minimal reproduction so not sure how to approach it.

[JMS55]

You can ask them, but a wgpu trace on macOS and another machine where it works would probably be best.

[Sigma-dev]

Do you know how I could get that trace ? I'm not very familiar with the concept

[JMS55]

You'll have to ask the wgpu devs https://matrix.to/#/#wgpu:matrix.org. I can't remember if wgpu traces were broken in wgpu 24 or not.
