The program is CATIA from Dassault.
They have a parameter to control the refresh of
the display (CATIAApplication.RefreshDisplay = False) but this
only works within their macro engine. For details see here:

I have a program which I can control via COM and Python's win32com.
This program will visualize a big tree, which gets created by my COM-commands.
The problem is, that after each modification of the tree (like insert), the
program
refreshes its display area.
Accidentally I discovered when you click on the window of the program
to change its size, as long as I don't lift the mouse button, the refresh of
the display
area is suspended and the performance of the tree creation increases by factor
10.
So my idea is now to simulate this event.
Most similar COM controls have APIs to suspend drawing while you make
large scale changes. Sometimes it's called freeze and thaw, sometimes
suspend and resume, sometimes other similar words are used. Have you
looked carefully through the COM interface to see if there is an
interface like that?
Is this some well-known program? Perhaps one of us can take a look at
the interface.
