Cursor appears for no reason when gaming with a controller

The cursor appeaers in the middle of the scvreen for no reason. I'm gaming on Big Pic Mode on Steam. And EVERY time I game I turn off my mouse & keyboard. So I'm at a loss. But this has happened a few times before. Just didn't get around to reporting it.Thankyou for listening & digging the game. If you guys can iron out this bugs. You might have a game of the year
