Game window completely glitched out
I was playing a normal game and suddenly got a ping spike, then my game tabbed out on its own so I tabbed back in and then i couldn't move or press anything (clicking and hotkeys). I'm not entirely sure how to happens but it has occurred more than once and has caused me to be forced to afk for 5-10 minutes. Most of the times relaunching my game or restarting my computer has fixed the issue. However, one time I completely had to reinstall league for it to work again.
