"Shift Window" is a nifty little tool which enables you to get rid of those borders/title bar and automatically centers it, effectively giving the same effect as playing it fullscreen.

I'm also aware of other games that have caused people issues whilst playing fullscreen, only to be perfectly fine once windowed. Hopefully this tool will help alot of you out there with some problem games.

 

So you can alt-tab(like u see in streams) and the game client remains there in the way.

 

Download the program
