Laggy Scrolling in Safari with MacBook Pro

The title says it all. Safari 5 is extremely slow scrolling on many webpages. The worst culprit seems to be sites that have flash video (read, any site with ads). Scrolling is extremely slow and jerky.

By comparison, both Chrome and Firefox are perfectly smooth on sites with Flash.

As far as I can tell, Safari uses some sort of hardware acceleration for scrolling. Both Firefox and Chrome peg the CPU pretty good when scrolling (especially with smooth scrolling enabled). Safari hardly uses any CPU when scrolling, but the scrolling performance is terrible. I've done everything obvious — deleted all preference files, used the "Reset Safari" command, tried it without plugins, etc. It's still bad in general, and horrible with flash on pages.

This is a MacBook Pro 2.4 ghz with the GeForce 8600M GT. Any suggestions would be appreciated.

MacBook Pro 2.4 GHZ C2D, Mac OS X (10.6.3)
