I am working on a program that causes the X server to grow by a large
amount (1-4 Meg/window).  The windows that are causing problems are
Motif graphics windows.  Scrolling is controlled by Motif, so the
window is retained.  That is likely to make it take up a lot of space
(1 Meg) since it is a color window.  However, depending on the
configuration of windows on the screen when the windows are opened,
opening a new window can cause the X server to grow by 2 or 3 meg in
the typical case.  If the old windows are mostly off the screen, then
the server only grows by about 1 Meg for each new window.

Does anyone have any idea why it grows in a screen configuration
dependent fashion?  If so, how can we minimize the growth of the X
server?  At this point, it probably is not feasible to rewrite the
scrolling so that we do it instead of Motif.

Thanks for any help.
