Hello Aerosys.
I localized an issue that I had, in the past. ..But I havent communicated my issue well at the time—including the unforeseen root of the issue! Explained in one screenshot. Its the only UI-related issue I have left. ;w; Thanks in advance!

I recently released a new version 1.7.0 of this plugin, which offers some new controls for the Target Actor Window (ie the window from your screenshot), and more will follow!
Does the latest update already help you yet?
This fixes the crunched letters and numbers issues. However, there's now parts made invisible! Ive spotted that issue in the spell-selection, spell-use and status menu. It goes without saying, its prob the same in the item and item-use menus as well. I've added extra screenshots to show what I mean here. 
As I wrote above, its probably due to my unorthodox screen and ui size/ratio. You can see them on the first comment's screenshot above if you'd like to replicate it on you end.
Now, one might say, "why dont you stick to default size of screen and ui?" Thats simple: To force a zoom and to keep the frame of it all at exactly 1 square/tile (I.E.: Nothing cut off screen by misalignment), to not have too much be seen by the player and finally, nostalgia. PS: Gwen's avatar not being seen is NORMAL: I just didnt make hers yet. Its not caused by your plugin.
