Summary: [WebGPU] MTLVertexDescriptor is not being correctly generated
Product: WebKit Reporter: Mike Wyrzykowski <mwyrzykowski>

Description Mike Wyrzykowski 2023-04-11 10:10:54 PDT 
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.
