I'd like to add the following:
I'm still using KDE3.5.10 on an openSuse 11.0, IBM Thinkpad T43 Laptop with ATI
 GPU and fglrx driver. kwin from KDE3 works smoothly when resizing windows.
For testing I started kwin from KDE4 (kwin --replace) instead of kwin from KDE3
- anything else is still running KDE3 apps.
Now, the same applications which were resizing smoothly with kwin/KDE3 are
suddenly resizing very slowly with kwin/KDE4.
So it is definitely _not_ an issue with Xorg or the driver.
Turning off desktop effects completely does not help either.

However, I see that the problem occurs only with applications which define a
hint for the wm to resize in steps and not in pixels (hope my wording is
clear).
E.g.: the slow resize happens with konsole(KDE3) or gvim but does not with
konqueror or kolourpaint(KDE3)

Move, minimize, maximize, restore is fast as usual.
