I found a problem that may be a bug. After typing many glyphs with different widths, Glyphs zoomed in and out of the view. The number of characters in each line would change. The change of character position looked really messy. I don’t know what caused this phenomenon. It really bothered me.
Can you post a screenshot of the full window?
Can you add one unit to the edit view with settings in Preferences.
What is the “Text View Width” in Preferences > Appearance?
We have improved on this behavior so it should be less jumpy in the 3.2 update. Until then, use a “Text View Width” that ends with a “1” like “8501”.
