Abstract
A window surface associated with a first application is automatically detected as an exclusive window surface for a display. In response, the system automatically transitions to a full-screen mode in which a graphics processor flushes content to the display. The full-screen mode includes flipping between a front surface buffer and a back surface buffer associated with the first application. It is subsequently detected that the window surface associated with the first application is not an exclusive window surface for the display. In response, the system automatically transitions to a windowed mode in which the graphics processor flushes content to the display. In windowed mode, the system frame buffer is flushed to the display. The transition to windowed mode includes a minimum number of buffer content copy operations between the front surface buffer, the back surface buffer and the system frame buffer.
