Screen Flickering While Playing Games (Edited)

[Giroof]

I am having two issues with this at the moment.

1) When I am playing a game in a window, my screen will flicker and show whats behind the window of my game, being the desktop. Every time I click, the desktop will flash up very briefly, almost as if the desktop and game are fighting to show up at the same time, and my computer cannot recognize which element I am trying to click.

2) When I am playing a game in full screen, the screen only flickers showing the desktop when I click inside the game, not randomly like with using a window.
Now, if I click inside the game several times, the game will completely minimize, not respond, and show my desktop.
My mouse will be hovering over the start button. I cannot move the mouse, yet I can still click and the start drop-down menu will show up.
The only way I can navigate from then on is by using the arrow keys, and ive been forced to restart my computer twice.

Does anyone know why this is happening, and/or what I can do to fix it?

Go into services and disable "Desktop Window Manager Session Manager". Switch it back on when you are finished in the game.
