KDE question

[Iassen]

I have the following problem:

When I startx (doesn't matter the resolution - 1152x864, 1024x768, 800x600) and open a window, everything seems ok.
But when I try to move the window, or scroll it up/down, my screen goes crazy (it results in something similar to a Picasso painting).
Xconfigurator recognizes my card and doesn't report any problems.
Can you hint me what to do?

My details are:

Red Hat 7.0,
Savage4 32 MB videocard,
KDE

I haven't downloaded any card drivers or anything else, I'm hust using the utilities that came with the RedHat distribution.

Thanks in advance.

Is this just in KDE, or in X entirely ?

Well, I've never tried anything else.
I will try with Gnome.
