Every time I try to open and play a game (Sniper Elite 3, Batman Origins) I get these black lines/borders at the bottom and to the right of the screen. This has started happening today, normally it never happens. This only happens in games, it's perfectly normal on desktop,running chrome, etc. I don't know what the problem is or how to fix it.
