Sadly it's not the bluetooth. I started with the xboxone controller plugged in through USB wirelessly, and was having the issues where the triggers wouldn't register as fully pressed, so you couldn't talk to people. Then switched to wired keyboard, and that's when the input focus started. I actually setup my bluetooth because the keyboard/trackball kept losing focus. Even does it to my usb wireless logitech f710.
It's annoying, but workable. Almost finished the game, and compared to what some people have had to deal with to get it to run, I can't complain too much. Other then this weird issue, and having to add an exception to avast, I've had a relatively smooth game... just wish i knew why it does this. Rockstar finally got back to my ticket with verify installation.... afterwards was less then five minutes before it happened again... it was actually worse afterwards then it's been in awhile
