My bad, I thought the issue was about quest titles as well, but if you mean the QuestLog Title then it should work properly as intended and is conflicting with something. Sorry to hear you'll have to go through a bunch of enable/disable but if you pinpoint the conflicting plugin maybe I can make a workaround patch!
Edit: It's also strange to have the text so pushed on the left as I placed a double padding check with the window size, maybe we can find the source of that problem as well
