I found an annoying little bug... I thought it was when I press an key combo (cmd+m, cmd+left, cmd+[insert key here]), but I just noticed it was after I press any key (except some of the "F" keys on the very top row) that the sides of the trackpad are apparently "off" and stay like that until I touch the middle of it. It's kind of a nitpicky problem, but I just wanted to see if this was happening to anyone else.
