The issue is fixed, but some background on the current situation:

Because of the async nature of the event loop, we need to recall() from the StagingBelt within an async function. Because of some of the state wgpu::util::StagingPool has internally, I'm not able to do this.

Instead I made a replacement that uses async channels and solves this issue: wgpu_async_staging

Additionally, wgpu_glyph requires the use of a StagingBelt in its public API. I had to patch wgpu_glyph to use wgpu_async_staging instead, and add this patched version as a submodule.

I'm not sure that this is the best solution, but I wasn't able to find a way to fix the concurrency issues using the built in wgpu::util::StagingBelt.

Thnx for the fast action!

I don't have any experience developing with rust myself other than building things, but the project looks interesting enough that I want to help test it at least :)

Thanks for the interest, I appreciate you testing it out and filing issues :)

It'll be a bit difficult to get some of the more advanced code I wrote for live performances to run because of the specific hardware I used, but I just published some simple examples which demonstrate the basics which anyone should be able to run.
