I have a random issues with the game. I have 3 monitors and when I close the game all monitors go black and I can't do anything about it. I tried the usual key combinations like ALT+TAB, CTRL+ALT+DEL and CTRL+SHIFT+ESC, nothing worked. The only thing I could do is push the power button of my PC to initiate a shutdown.
