I would like to briefly jump into the discussion here and
point out that the application that Stephane C. has trouble 
with is commercial software for developing silicon chips.
This tool can potentially draw an awful lot of graphical 
elements (the chip layout) which easily takes several 
seconds over a LAN network, and can take a lot longer. It 
also wants to redraw the window contents when it is resized. 
You can understand that it quickly becomes unusable if during 
the resize it has to refresh several times. We really like to 
use Gnome+metacity as our desktop, but it should not slow down
our work. And unfortunately we have no alternative for the
software we're using ...
