We solved this outside of the forums, but here's the solution:
1. This is something already in the "notes" section of the docs! "Tabbing out of the Unity editor and back in might cause a text mesh to redraw. This does not happen in builds. To disable this in the editor, go into Preferences, and turn "Auto Refresh" off!" So... that's the solution! It doesn't effect builds.
2. I submitted an update that hopefully fixes this. Fingers crossed!! 🤞
