gutsy glibc causes graphical corruption with nvidia driver

After upgrading to gutsy's glibc, i found most (if not all) of my games experience low to severe graphical corruption. I just upgraded my laptop from feisty to gutsy and when i booted it back up to try the latest wine, i noticed i had graphical corruption in all of my games. At first i thought it was a new bug in wine, but it happens in UT2004 (native) as well, although it's very low there. The problem goes away when i downgrade to feisty's glibc. It mostly looks like some kind of snow effect (random pixels or groups of pixels being the wrong color in certain parts of the screen). I'm using the nvidia driver provided by the restricted modules package.
