Raster rendering mode covers glyphs with blocky artifacts

Environment

  • Caxton version: 0.4.4
  • Minecraft version: 1.19.4
  • Fabric Loader (or Quilt Loader) version: 0.14.19
  • Fabric API (or Quilted Fabric API) version: 0.80.0
  • Operating system: NixOS unstable

Summary

I had a working MSDF font definition, which I tried changing to use the new raster rendering mode, but this appears to cover the font's glyphs in large blocky artifacts.

Steps to reproduce

Install this resource pack, then go to the language menu and look at the entry preceding Quenya.

Expected behavior:

The font should appear largely the same as it does when using the MSDF rendering method: Screenshot_from_2023-05-26_14-33-45 (but hopefully with crisper edges)

Actual behavior: (What happens instead)

Blocky artifacts Screenshot_from_2023-05-26_14-32-04 I tried tweaking options such as blur, shrinkage, invert, margin, range, max_mipmap, but none of them appeared to affect the artifacts.
