Vulkan SDK 1.4.309.0 with MacOS 15.4.1, "SPIR-V to MSL conversion error"

[rgobbel]

This is similar to the previously reported error with Vulkan 1.3.268.1, but not exactly the same. Trying to run the widgets example, I get:

[mvk-error] SPIR-V to MSL conversion error: Argument buffer resource base type could not be determined. When padding argument buffer elements, all descriptor set resources must be supplied with a base type by the app.
[mvk-error] VK_ERROR_INVALID_SHADER_NV: Fragment shader function could not be compiled into pipeline. See previous logged error.
panic: vulkan error: vulkan error: invalid shader (NV) (-1000012000) on /Users/gobbel/go/pkg/mod/github.com/goki/vgpu@v1.0.34/vgpu/errors.go:23 (0x1047eccef)

I haven't tried another version yet. I'm trying to run the axon version of PVLV, running into some problems with that, tried to install a new Vulkan SDK in the hope that that would solve those issues, but obviously not.

Hey Randy -- the current axon version of PVLV does not depend on vulkan! It is running webgpu now, and runs on cogent core: https://github.com/cogentcore/core -- anyway, use an older version, e.g., 1.3.283.0 which is what I have on my system and it definitely works.
