kslideshow screensaver transitions slow in f16

[Gene Smith]

I recently upgraded from f14 to f16. Some of the kslideshow transitions 
are now painfully slow, especially ones where one pictures fades into 
another. These were fine on f14. Any idea what would cause this?

I removed the configuration file ~/.kde/share/config/kslideshow.kssrc 
and re-entered my configuration (after logout/in) and it didnt' help.

Otherwise, graphically, the system seems fine.

(Seems like I remember seeing this same problem many KDE versions back 
it it eventually went away.)
