# Objective
- Actually use the value assigned to `d_xz`, like in [the original SMAA
implementation](https://github.com/iryoku/smaa/blob/master/SMAA.hlsl#L960).
This not already being the case was likely a mistake when converting
from HLSL to WGSL
## Solution
- Use `d_xz.x` and `d_xz.y` instead of `d.x` and `d.z`
## Testing
- Quickly tested on Windows 11, `x86_64-pc-windows-gnu` `1.79.0` with
the latest NVIDIA drivers. App runs with SMAA enabled and everything
seems to work as intended
- I didn't observe any major visual difference between this and the
previous version, though this should be more correct as it matches the
original SMAA implementation
