wine - Diablo 3 and Starcraft 2 fullscreen with system bar ( ubuntu 14.04 )

I'm running diablo 3 and starcraft 2 , and when my game starts, the system bar is showing up on the fullscreen but before the game open in the desktop of the wine the bar does not appear.

I want to play on fullscreen without the system bars.

System: Ubuntu 14.04
PlayOnLinux 4.2.5
Wine 1.7.22 on Starcraft II
Wine 1.7.15 on Diablo III
