            Bug ID: 255291
           Summary: [WebGPU] MTLVertexDescriptor is not being correctly
                    generated
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mwyrzykowski at apple.com

Open https://data.runhello.com/j/wgpu/1/

Note the validation error: Error Domain=CompilerError Code=2 "Vertex attribute in_color(1) is missing from the vertex descriptor"

It would seem that:

  static MTLVertexDescriptor *createVertexDescriptor(WGPUVertexState vertexState)

is not correctly implemented. The shader source appears correct.
