The graphics plane does not support XRGB8888, which is the default mode X uses for 24-bit color. Because of this, X must be set to use 16-bit color, which has a measurable performance penalty. Make the video plane the primary plane as it natively supports XRGB8888. An alternative approach to add XRGB8888 to the graphics plane is discussed in [1], as well as in patch 2.
