The toggle D3D12ForceClearCopyableDepthStencilTextureOnCreation can be disabled when the toggle D3D12Allocate2DTexturewithCopyDstAsCommittedResource is enabled because with D3D12Allocate2DTexturewithCopyDstAsCommittedResource all the depth stencil textures (can only be 2D textures) with CopyDst usage have already been created with CreateCommittedResource() instead of CreatePlacedResource(), thus the driver issue about creating depth stencil texture on a dirty heap with CreatePlacedResource() won't be triggered.

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.
