Hmm, maybe it was from having a controller plugged in? I unplugged a controller and it went back to normal. Weird bug. Sorry I can't be of more help. Doesn't seem to be an issue for me now.
Maybe it was the cause. I don't have any input coded to work with a controller because it isn't popular in my country and I don't know how to use it. Maybe something in the input system is affecting the controller somehow. I'll give it a check later.
