I am experiencing similar issues with the latest server kernel, KDE installed over the top, Xorg 1.9.0 from stock repositories. The desktop will lag severely for a few minutes, even switching NumLock/CapsLock takes awhile to register. Have found issues describing similar problems mentioning problems with nVidia drivers, but that is not the case here. Nothing relevant in system or app logs.

On occasion, switching to terminal via Ctrl+Alt+Fx will lag for some 10-15 seconds, then operation through there is as quick as ever. top/htop reports heavy system CPU usage, but almost no processes report using the CPU. Sometimes (but not consistently) when the issue clears up, dialog appears stating desktop effects have been disabled due to unresponsiveness. Will attempt to disable desktop effects and see if that helps.
