Ever since upgrading to 9.04 last weekend, all the kde applications (konqueror, konsole, kmail) are laggy, slow to respond to keyboard or mouse events like typing or dragging the scrollbar. alt-tab switching between applications or switching desktops are also laggy. Interestingly, firefox doesn't seem to be affected.
Top shows the X server running between 25% and 50% of cpu, even when the box isn't doing anything except redrawing the screen for top.

stracing the Xorg process locks up the whole box, forcing a power-button reboot.
I've tweaked all the X settings I can find, and none of them seem to make any difference.
Any suggestions? Anything you could add would be extremely helpful. Thanks!
