Comment 1 for bug 511872

Oddly enough, I had the same problem with the Sevenmachines PPA NVidia drivers and when I switched tonight to the nvidia-current drivers 180.53-0ubuntu8 OpenGL compositing does finally work with KDE (hooray!) but 3D applications do not (boo!). Try upgrading to 180.53-0ubuntu8 and see if the compositing does work again as it does for me, although it leaves me with an odd choice. Sevenmachines PPA and 3D apps will work but compositing will not or nvidia-current where 3D apps do not work but compositing does. The joys of testing!

I'll be a second voice to say that there is a problem where OpenGL 3D applications with Wine and native programs do not work with nvidia-current.
