I can repro with Vulkan as well as D3D. I'll have to check whether the software renderer or the 3D renderer is correct.

These 4 also fail on Metal:

OpenGL and the software renderer pass everything.

The "gpu" backend passes everything, too, on both Metal and Vulkan.

9b454a7 fixes metal and the D3D renderers, and a036aed does the final step to fix this for Vulkan.
