Hey buddy, sorry to hear it's still not working properly for you...
Have you tried resetting the plugin? (Deleting it, saving the RPG Maker MZ editor, and reinstalling the plugin?)
Because I tested it with the resolution you mentioned, 640x480, and it's displaying fine for me:
If you'd be so kind as to share your graphic settings and the resolution you have set in RPG Maker MZ—both the Screen Width Size and the UI Area Width/Size—that would be ideal so I can replicate it on my end.
And if you can tell me which texts you want to make smaller or larger, even better—I can give you a quicker and more direct solution that way.
If you want to attach photos or a video, that will also help me understand it better. Thanks a lot!
