Thanks for the reply.

I'm not sure, because it occurs in KDE 3.5, without any window effects.
And once again, even if it is not dramatically sluggish, it is for sure
slower than xorg 6.8 XAA.

When I switch desktops with a lot of KDE windows on them, it takes more
than 1-2 seconds to complete and xorg burns a lot of CPU.

Btw, same with Kubuntu 9.04 with KDE 4.2 (without any effects). When I
switch desktops, Dolphin or Konqueror windows take one or two seconds to
reappear completely...

How can I see more precisely what eats CPU inside the Xorg process ?
