I have been having this problem with Unity games for a while now on stable and beta steamclients. I first noticed it in Rust a few months ago and it is now happening in Golf with your friends, Armello, Layers of fear, white noise 2 and Human: fall flat.
In rust, layers of fear and human: fall flat and white noise 2 I can take 1 screenshot per session and then no more until restarting the game.
In Golf with your friends taking a screenshot causes the games graphics to freeze.
In Armello screenshots don't work at all, but the overlay in general doesn't seem to work right in Armello.
Nothing extracted yet.

Please describe your issue in as much detail as possible:
Taking more than one screenshot in a short amount of time makes the game crash/unresponsive
