I just installed FB 4.7 on two Windows machines. A desktop with a 4k display, and a midrange Samsung laptop. On both systems, the UI is making the text and other elements way too small to read. Especially on the 4k, it's a joke.
We have all seen this before on other Adobe programs, but most have sorted it out (more or less). But I don't see any pref options to fix this in FB.
