Angry Unstable and garbaged screen

I have this really stupid problem with my Nvidia (GF2Ti) card. As you know, you can select between the regular generic "nv" driver that comes
with X, and the 3D accellerated nvidia-driver from nVIDIA. My problem is when using nvidias own driver. It is highly unstable, more unstable
than I've ever heard anyone telling before. It's not just it's unstable, also nicely spread around graphical intensive things on the screen,
there appear some "error-fuzz". Interference of some kind. My screen looks horrible sometimes, especially when using the Option "backingstore"
in XF86Config (which some kind of 2D accelleration i presume). I can use my PC with that driver, but it's annoying when garbage appear all the time.

Typically those interferences appear imidiately after running an OpenGL application (like Quake III, XMMS vizualisation e.g.). Ironicly those OpenGL
applications windows run perfectly (if not, the nvidia binary driver would be total useless for me). When moving the standard OpenGL
XMMS visualization (colorized bars) around on the screen while it's running, it leaves trails behind on the root-window. When browsing the web, loading
pictures is terrible. Some symmetric lines mess up the pictues while its loading(, but when it finishes it repaints fine). You can imagine what
scrolling pictures look like. When I'm surfing pages with much or complicated graphics X often freezes and theres nothing I can do
locally. Print screen (command: import screenshot.png) saves a file with symmetrical errors on the whole picture. I've seen similar problems before.
One time i solved it by setting the AGP (transfer rate?) from 4X to 1X in the BIOS. That does not work for me. If my problem would appear in Windows,
I would decrease the hardware accelleration (Desktop --> Properties etc.) I don't know why Windows has so many steps, not just "no 3D accell" and
"yes, 3D accell". For me its anyway Driver "nv" or Driver "nvidia", as i know.

I think this is a really strange problem. Since X starts fine it thinks for itself that everything is okay. I think there's no way for X to realize my problem (discover those error-dots? i think not), so there's nothing strange in the logs. I don't have Windows installed, but when I had some time ago, i think the problem was present there too (Win98). But i don't think Windows XP has it. I really should try to install it and have a look.
Maybe this is some bad combination of chipset or so?

I convinced that i'm the only person on the planet having this problem, so if you can proove me wrong, i would appreciate it. I thankful for whatever help i can get.
One more thing I should try:I have a friend with NVIDIA GF4MX??, maybe i should ask him if we could switch graphics card sometime...
I've testet the nvidia-driver in RedHat Linux 9 too, and it's exactly the same problem.

I run Debian GNU/Linux stable
XFree86 ver. 4.2.1
Downloaded the newset nvidia-drivers today (noticed that the kernel module has a new name: nvidia, not NVdriver)
Motherboard: Aopen AK77.
Graphics card: MSI NVIDIA GeForce 2Ti (or 2GTS)
