Current UI mods will need to be updated to reflect the new default fonts, or use their own.
In the meantime, your options:
- Open the font files (FontZapf15.xml, etc.) with notepad, reduce the PointSize values, and save to your custom UI folder.
- Grab the old font files from Jaxel's OCD complete set (
