consider switching to the proprietary NVIDIA driver. *** This bug has been marked as a duplicate of bug 309280 ***
Switching to proprietary NVIDIA driver solves the issue, but it's kind of weird: A few month ago I was told that the proprietary driver higher than version 304.88 doesn't support my video card anymore. Trying to emerge nvidia-driver-304.88 resulted in an error without support (gentoo only supports the nvidia driver up to kernel < 3.7). That's why I switched to nouveau. Actually emerging nvidia-driver-304.88 works with kernel 3.8.5. Don't know how long this will last, but for now everything works well.
304.xx is legacy but not unmaintained. You'll get updates to match recent kernels/XOrg versions. Potentially with (increasingly) more delay than the mainline blob, though.

Vielleicht lässt sich ja das Fehlverhalten eleganter durch einen zukünftigen Patch beseitigen ! Thanks a lot, Harald Huber
The problem is that the patch is in the driver (even if KWin would do really really wrong by -actually- ignoring limitations, which you should however rather not hit on that GPU, the GL call should yell an error, but no way crash), so a patch could at best blacklist the driver. Now, the particular issue about the nouveau drivers is that their OpenGL implementation is not considered "reliable" and you're actually supposed to expect issues [1], so they'll be rather used by developers and driver testers - therefore blacklisting explicitly them would be rather not helpful. Upstream bug *might* be https://bugs.freedesktop.org/show_bug.cgi?id=56474 (do you have that chip?) [1] http://nouveau.freedesktop.org/wiki/MesaDrivers
