Hi!

I want to do a fast, fluent animation with XFree86.

To avoid tearing effects, I need to do two things:
  1) Use some sort of double-buffering technique		DONE
     (I use Xdbe or a pixmap+XCopyArea for that)
  2) Synchronize the swapping of the buffers with		TBD
     the vertical retrace of the screen.

Only a few drivers actually wait for vertical retrace before swapping buffers that I know of, and they are all OpenGL drivers.
