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.

Out of the blue (although I might have missed some automated update), the flip() method of pyglet on my P.C. became about 100 times slower (my script goes from about 20 to 0.2 FPS, and profiling shows that flip() is to blame).
