Ah, okay. I didn't realize it was an exclusive a PS4 thing as the process on consoles repaired the text size issues we were having.

The way OP describe it sounded like a dead ringer to what I saw before the fix as my personal solution before 4.1 was to enlarge other UI elements manually and do the single chat text trick, since the text chat remained seperate.

Since so many other UI elements have been broken up and the UI can be even larger, is it possible NPC text is just really buried now? Otherwise, the option may have been lost in the shuffle.
