To avoid uninitialized reads of depth stencil data, where the Metal driver incorrectly binds/loads the wrong depth stencil subresource, always keep all depth stencil subresources initialized. This means that textures are initialized on creation, and StoreOp::Discard is never used - Store is used instead. Texture initialized state is still set as-if the Discard occured, so Dawn will try to zero-initialize the subresource if it is read from. In many cases, this will work correctly, and the application will read back 0, as expected. In some cases, Metal will bind the wrong subresource, and the previous contents will be read. This is wrong, but at least it is not uninitialized data.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
