I have tried this before but forgot mentioning it. For the program considered
(plotting a moving bar diagram) this works, but only in a part of the window.
Beside this, the whole X screen behaves strangely, with changes (e.g., the
WM menu) appearing ghostlike only in the surrounding of the mouse pointer.

Well, one should not rely too much on backing store, but on other servers,
it works sufficiently well.
