I just posted version 3.1, build 3 that fixes all issues noticed when running in MacOS Sonoma 14.3.1. I personally tested this version in High Sierra, Mojave, Catalina, Monterrey, Ventura, and Sonoma (those old Mac still have uses) and all look fine. Even if build 2 is working OK for you, this new version is still recommended. It has to other minor changes (such as to the Default Format).
In brief, it turns out Apple decided to redo the way they render text fields in Sonoma. It is buried someplace in release notes.
