G400/450 Screensaver corrupts output when reactivated

Hi,
I have a strange problem on a site using Matrox 400/450 with driver
version 5.72.21.0 and Matrox Millenium G550 has driver version
5.72.21.0.
The screen is corrupted after the screen saver has been active and is
turned off. The to of the screen is a character set with white text on
black background while the bottom is a garbled/duplicated parts of
what the screen should display.
Anyone heard of this problem before?
The site use a standard screen saver.¨

thanks/Patrik Sjogren

The screen saver is the OpenGL moving objects.
Does Matrox recommend not to use OpenGL screen savers?
