Bug Description

With Caxton 0.5.3+1.20.4 and Sodium mc1.20.3-0.5.5, the interiors of glyphs in outlined text have the wrong colors. (For running in Sodium’s dev env, 33891cf for 1.20.4 or ffc0228 for 1.20.2 is required).

With Caxton and Sodium:

With Caxton alone:

I’ve traced this issue to commit fae888e. The optimized BufferBuilder implementation introduced by this commit seems to assume that any vertex format has at most one color component. Meanwhile, Caxton uses a custom vertex format with two color components to render outlined text (see CaxtonVertexFormats, CaxtonTextRenderLayers).

Reproduction Steps

1. Start Minecraft with Caxton and Sodium installed
2. Enable the bundled “Sample Font: Inter” resource pack
3. Enter a world and place a sign with glowing text

I really don't see how it would be possible for us to fix this. And that's a shame, because I actually have used this mod in the past to deal with Minecraft's very illegible font. Having multiple semantic elements of the same kind doesn't make a lot of sense (at least given my understanding of how you are using them), but I will have to think more about it after the holidays, and see if we can do something to not break mods like this.

#2240 will likely be enough to fix the problem with Caxton.

Resolved with 1cc23f1.
