But maybe some component (updated) connected to the driver (Xorg, Kernel, ..., kwin?) is able to trigger these problems? Imo the high X cpu usage is kinda suspicious.)
KDE: live trunk build (some days ago; >=20090428); Qt 4.5.1 (with qt-copy patches)
xorg-server: 1.6.1

I'm having these problems for some weeks, don't know if this can be a kwin issue (anyone who knows?)
I also has the same VGA card like you (8600M GT), same nvidia driver version (185.18.04), xorc-server 1.6.1, QT 4.5.1 and KDE 4.2.2 but I have no problem with Kwin/OpenGL mode at all. Hovering mouse over those buttons only make X consume 2~4% CPU
