A computer-graphics technique for updating a dynamic image that greatly reduces the visual artifacts, especially flicker, caused by the screen pixels being changed. The new image is drawn in a "hidden" buffer while the user still sees the old image, stored in a "visible" buffer (hence "double-buffering"). When the new image is fully drawn, the visible and the hidden buffers are switched very quickly and the hidden buffer content becomes visible.
