This also happens to me. It's kinda funny, I was just about to make a topic when I saw this.
I don't restart, I press the power button on my PC which bring up the shutdown menu. I press ESC to exit the shutdown menu, then press CTRL+ALT and right, to move to desktop 2, then CTRL+ALT and left to go back to Desktop 1. I then move my mouse and it goes back to full screen and I have mouse control... but this is annoying when I'm being shot at. I try to tell people what happened but they don't care/believe me.
So, that was just a really long drawn out way of saying. I would also like help with this.
