Public bug reported:

Binary package hint: kdebase-workspace

Yesterday, without any warning, some of the graphics rendering
operations on KDE 4.3 became incredibly slow.  The two most noticeable
are the desktop icons/folderview icons, and anything related to the
Plasma panel and Kickoff.  Mousing over the desktop icons shows obvious
lag between when the icon selection background should appear and when it
actually does.  Also, the translucent selection rectangle, which was
before liquid smooth throughout the entire range of travel, now becomes
unusably slow if any icons are selected.  Also, widgets in the Plasma
panel (Quicklaunch, the K menu button, etc) now show quite a delay
before they light up.  In Kickoff, the selection indicator also lags
significantly behind the mouse cursor.  If you select an icon and try to
move it, that lags too.  Finally, the animated switching of panels
inside Kickoff is slow and laggy.

I did not update any relevant packages that might have caused this.  I
have an nVidia 8600m GT with the 185.18.10 drivers, but the problem
occurs with any driver version.
