A compiz question

I just installed the new nvidia driver 177.70 BETA on my opensuse 10.3 with KDE 3.5. I’ve got a geforce 8400 GS and now everything works better, even with compiz running!

The problem cames when I ran kdevelop, kate, kwrite! Because of compiz the WM is not drawing well the windows and this 3 programs (that I’ve tested) are shown with deformations.

What can I do to solve it?
