There are a couple of ways, but unfortunately they may not be to your taste ... 1) Use windows (where double-buffering has been implemented) 2) Find some way to convince someone to modify the X11 device (or whichever device you are using) to support double-buffering 3) Provide a patch for the X11 device yourself ...
