We wait a long time for the server side pixmap to be copied to the
client side. If we scaled in the server side instead, we transfer a
much smaller pixmap. We may save as well some implicit format
conversion that may happen inside gtk.

You mean scaling in the server? I wrote the code attached to the
ticket about one year ago and then ran out of time before managed to
have it working reliably. May have been a bug in the driver (that may
have already been fixed), or just me not getting what X hacking is
If someone could give it a try, may be worth it.
