nVidia random speckle noise

This issue is rather weird, but it only happens sometimes, so it's not really a huge problem. It's annoying, though.
A screenshot would better explain what happens :

As you can see, there's a huge speckle noise on the screen... It usually happens after a few hours, and usually when I'm using the GPU for video decoding (VDPAU). Desktop is still fully responsive, and I can do everything I want, except I can't see with that crap on my screen. I'm guessing those symptoms would indicate a memory corruption of some sort in the nVidia driver, but I don't really know how to fix it...

Did someone here have the same issue once? Did it get solved? If so, how?
Thanks for sharing your experiences

see if downgrading the xorg-server helps.
