The games cpu usage drops a lot when the window is fully covered. I guess 1.8.3.1 caused this, but I never really payed too much attention to that.

One thing I noticed though is that it stays high when the window is minimized or on another desktop. Is that a problem of the window manager, the game or is that just the way things work? My wm is e17.

It's not a serious issue but I wouldn't mind if I could minimize the window and free up the processor.
