Methods and apparatuses to accelerate scrolling for buffered windows. In one aspect of the invention, a method to scroll a buffered window on a data processing system includes: determining a second region of a second pixel image of a window in a frame buffer, which corresponds to a first region of a first pixel image of the window buffered in a window buffer that is scrolled from a first position to a second position in the first pixel image of the window in the window buffer; and scrolling the second region in the frame buffer to synchronize the second pixel image in the frame buffer with the first pixel image in the window buffer. In one example according to this aspect, the second region in the frame buffer is scrolled using graphics hardware; the frame buffer is located inside a video memory under control of the graphics hardware.
