Xcode GPU capture missing initial buffer data
I'm using the WebGPU abstraction library wgpu to build an app using compute shaders that compiles to Metal (on macOS), and in certain patterns where it uses a staging buffer for initial data, the data is just total missing from the capture, breaking other workflows such as shader debugging or seeing the completed results in the final buffer. I wrote up details including a repro project and screen shots of the issue at https://github.com/gfx-rs/wgpu/issues/8111 . Seems like an Xcode bug. Any ideas? I'm happy to help investigate further if I can.
