Comment 26 for bug 144216

I've been checking this thread every once in a while for updates for this problem, since I really want to be able to use Emerald over k.w.d. or metacity. The 169.12 driver update sounded promising based on the last couple posts, so I just installed it.

Unfortunately, I can report that this does not fix this problem for my setup: Kubuntu Gutsy, Dell Inspiron 1720, GeForce 8600 GT. Any non-pixmap emerald theme is still very slow on tab switching in firefox/eclipse and in minimization animations.
