When moving in the game, the white text moves with the camera, creating another copy of the mob name.
For reference, i only have 3 mods (this, fabric-api and midnightlib), no texture packs, and no shaders (playing in 1.20.1 but i tested in 1.20.4 and the same thing happened)

If i add FOV to the game, the white text broke in the same way

I know this has already been marked as a bug, but just wanted to confirm this is happening with health text as well. I am having the same problem. Text is rendering outside of the box on the combined bar setting. (1.20.1)
