I am trying to run sample application "fgl_glxgears" provided with ATI catalyst driver on FC15. I modified "fgl_glxgears" such that the window created is full screen i.e 1366x768 and setting the "override-redirect" flag such that all events go to this window. But when I do these changes the screen starts flickering. Whereas if I just reduce the window size to 1360x768 it works fine.
Could anyone suggest what is the problem?
