Jittery mouse. Severly affecting game.
My mouse works perfectly fine anywhere outside of league. But as soon as I load into a game, my mouse will either immediately start messing up, or it will take a few seconds. Either way, it does this nowhere else. It will sometimes let me play okay for a few seconds, but then I'm useless for 3-8 minutes until it starts working okay again, for another few seconds. It has been much worse tonight. Severely in need of a fix for this.
