I have i strange problem.

The game was at full display and infront of the toolbar and was like any other game. But then my a massege showed up indicating that my battery is at 7% and after that i can't get the full screen back nither the toolbar behind the game.
I have tried the auto hide option for the toolbar that did work but still the game is not full screen and is slowing down when i play it. Also the auto hide for the toolbar did worked but the upper controls of the game did not disappear.

As i said there was no problem before that massege showed up and now it can't get it back.

What to do?

Got it to work.

Gone to system setting's and turn off the main display and the graphic card after 15s it turn back on and i sterted the game and it was working and in full sreen.
