What happened?

When using Fabulously Optimized (beta 2) with sildurs shaders and then adding this roboto font it makes all nametags (player and animals) red and have a black fill.
If I turn off either the font or the shader it goes back to white.

Brought this issue up with the font pack creator and they said it seemed like an iris bug.

Could you try with just iris and robofont please. There could be incompatibility somewhere else

Same behavior with only Iris 1.1.1, shader, font installed on fabric 0.11.6
