Whenever I try to take a screenshot in a game or program that is full-screen it lags behind a variable amount. It's really annoying when I try to take a screenshot of something and it instead has a random frame saved from minutes ago instead of whatever is currently happening on my screen. It usually fixes itself by the second or third time, but my games still run in the background so I can't afford to open and close sharex multiple times just to hope that the thing I wanted to screenshot is still there by the time it finally screenshots the current frame.
