Please try solid resizing with IPP=2 and the window decorator disabled, to see how much of an effect it has. Improving the performance of convolution filters and redirected window resizing in general is something we're working on for future driver releases.
Also, you should see a significant improvement in redirected window resizing performance with IPP=1 if you use one of the xserver 1.5 prereleases.
Just for fun, I tried this option and it absolutely KILLED my X performance. On "1", it FLIES, 2 is awful. VERY WEIRD!!!
