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.
