Hello. I recently made a modpack for me and some friends to play on and an old issue resurfaced. When ever I move my mouse in any direction, after a second it will jump. Like it speeds up and moves all the way across. And it makes the game almost unplayable. This only happens with forge not in vanilla. I have tried fixes such as making java a below normal priority. Doesn't work. Changing my mouse polling rate. Doesn't work. Turning off mipmap levels. Again, doesn't work. Does anyone have any idea if a mod could be causing this, or if there is a setting I should turn off?
