I use wgpu 0.14.2 and smaa 0.8.0

smaa.shader.edge_detect.vert(260,5-42): error X3017: 'SMAAEdgeDetectionVS': cannot convert from 'float4[3]' to 'float4''

That's weird, I don't observe any compilation errors with wgpu 0.14.2. Does it happen when you run the tests in this repository, or only within your own application? Some other things to compare:

  • Are you using naga 0.10.0, or is it getting patched somehow?
  • Do you enable any optional feature flags of naga or wgpu?

I'm writting a game engine and I'm trying to add smaa. With cargo.toml which looks like this:

wgpu = {version = "0.14.2", features = ["glsl"]}
naga = "0.10.0"

it doesnt work like before. Could this shader not work on older graphics cards?
I have AMD Radeon HD6300m and that can be a problem

sorry for my bad english

So, I looked into this a bit. I believe that "error X3017" is actually coming from your graphics driver. Which means that either (a) your GPU is too old and cannot support the shader, or (b) naga / wgpu corrupts the shader before handing it off to the graphics driver.

Ye, thats for sure, thanks
