The images inside the book get offset weirdly when viewing at different screen resolutions.
Text seems to render correctly, however.

Mod version: 0.1.0
Forge version: 1.12-14.21.0.2331

I can also say that the book "Broke" but I don't know if I should make a seperate issue about it

haha, that's weird

thanks for bringing this to my attention; something to stamp out while forge fixes other things in the meantime :]

EDIT: fixed in version 0.1.1 for Minecraft 1.12. Will retroactively do the same for versions before this, since the issue is present throughout them as well
