HONK! 3a is having what we like to call Phantom Talking™ going on. The mouth just kind of, going off on it's own.
Example, I use Hexels (art program), or any program, the mouth just starts going off, despite no audio input, even with mic muted.
Update 1: I think it it may have to do with multiple monitors, somehow. I noted when I move said program to any other monitor then my main one, the bug isn't going on, or rather, so minimal it's not really note worthy if it is.
If I make my primary monitor another one, it doesn't seem to happen anymore. I'll be fiddling more with this to see if I can't find a work around until an official fix is done.
Edit1: Reworded bug
