Hello! I have been using parallels for a year or so without any problems. One or two updates ago I started getting a lot of lag whenever I move my mouse around in parallels. I have optimize for games on (otherwise the scroll is all wonky) but it's the same if I turn it off. Any idea what the issue might be?
