Note that it might take a couple seconds for the update to show up after the preview_build workflow has completed.

Is the wgpu version upgrade blocked by something? I'd be interested in pushing this as I need it for an own project. Can I help somehow?

Currently the issue seems to be that wgpu is now no_std and the macro from the puffin crate still pulls in std components in the expanded macro (like std::sync::OnceLock) which doesn't work with no_std ofc. I will probably take a look at fixing this later today. (The demo app does compile without the profiling/profile-with-puffin feature so that seems to be the only blocker besides the macOS Issues)

@torokati44 should I open a different PR or should I edit your existing one (If you give me access to the branch)?

I’m not sure which crate should host the fix. The underlying issue lies in puffin, which is currently unmaintained, so the patch could land in one of four places:

• the egui-examples crate the error is happening in (other egui users will likely hit the same problem),
• the egui crate itself
• wgpu, or
• the profiling crate.

@Kumpelinus I think it's easier if you open your own, I won't mind. I don't think this permission can be easily granted to you.

Ok, will do 👍

I think bumping arboard will fix the duplicated core-* dependencies

Are you sure? I wasn't able to do it that way...
