Hi,
I have an application that must run in fullscreen mode, as I require synchronization of the framerate with the screen update rate. This works well under older systems, up to Windows 7, but I am unable to switch into fullscreen mode in Windows 8.

video_switch and video_screen do absolutely nothing if used after the first frame.
If called on the first frame, they both cause the screen to rapidly switch between the desktop and a black screen, and then the engine crashes because DirectX could not be opened.

Is this a known problem?
