page flipping in XFree DGA

Hi again! Although I've managed to remove the tearing artifacts in our dga program, the rendering speed (fps) is slow. I'm planning to use page flipping in our code but the program hangs when we run it. This is a part of our code that do the page flipping: //change the memory

RE: DGA and tearing effects
