Operating system & version

Windows 10

What you did

Run this below from a Windows 10 work environment to reproduce:

$Env:RUST_LOG="warn"; cargo run --example texture_atlas

What you expected to happen

No warnings to run at all, even though the example ran fine.

What actually happened

These warnings popped up while running the above command:

Nov 16 21:30:15.330  WARN wgpu_core::device: Failed to parse shader SPIR-V code: UnsupportedBuiltIn(4)
Nov 16 21:30:15.331  WARN wgpu_core::device: Shader module will not be validated
Nov 16 21:30:15.536  WARN wgpu_core::device: Failed to parse shader SPIR-V code: UnsupportedBuiltIn(4)
Nov 16 21:30:15.536  WARN wgpu_core::device: Shader module will not be validated

I don't exactly have too much input on how this could be fixed or what exactly went wrong as I lack the experience. Just noting it.
