Will "double-buffering" help? And how to do animation on a PEX-SI
server with no "double-buffering" support? And how to do that on a
Sun's server with d.b. support?

Thanks in advance.

yes double buffering helps in doing animation.
With the PEX-SI server you can do client traversal and use the
multi-buffer extension to control the double buffering.

Public fixes will be available in the not too distant future
to provide double buffering in the server workstation object.

The PEX-SI server can render to pixmaps, so I suppose you could
also pass a pixmap as your target drawable and then copy
the pixmap to the window at the end of each frame.
