So, Johnny keeps saying "Ha, House is really raking it in..." every time I load and the cinematic subtitles won't go away unless I turn the subtitles off.

Anyone else having this issue or now what's triggering this?

This solution on the steam forum helped me with the same problem:

FIX: Just quicktravel (or go) to Claredon St. on the south-west corner of Watson.

Thanks! I completed the quest in the bar previously and actually completed it a second time (two implants?!). He never finished the line, but hopefully it did the trick.

In a bunch of Johnny missions, I'd get a UI glitch that formed a persisting bar right where the subtitles were supposed to be. Must have something to do with the UI changing from red (V) to blue mode when playing as Johnny.

Saving and reloading fixed that for me.
