To reproduce:
1. Create new project
2. Add cube to scene
3. Change cube material to SpatialMappingWireframe
4. Notice that console is spammed with:
Metal: Error creating pipeline state (VR/SpatialMapping/Wireframe): Link failed: fragment input user(TEXCOORD0) was not found in vertex shader outputs
(null)

Expected: Errors shouldn't appear after changing material to SpatialMappingWireframe

Reproducible 5.6.0a5
Regression introduced in 5.6.0a5
