KWin (KDE4 from rawhide) using way too much CPU

I believe many of the KDE users here might be using the rawhide build of
KDE4. I have been updating to every new build of KDE hoping that more
and more problems are going to be resolved. Thankfully all the major
issues with KDE4 seem to be getting resolved but there are still some
things that still look strange to me.
When I enable Desktop Effects kwin and xorg take about 30% of the CPU
each. kwin sometimes takes as much as 80%, this is slowing down my
machine heaps. Although I could just disable the desktop effects and
resolve the problem I would rather give feedback to any KDE/Fedora
developers out there and assist with the resolution of this issue.
My machine is an "Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz" with 4GB
of RAM and a "nVidia Corporation GeForce 8400M GS" with 128MB.
I am running Fedora 9 x64 with the most up-to-date packages available
through yum and the latest KDE4 from rawhide. See below two snapshots of
TOP while my machine was idling.

I also would like to assist with testing KDE4 but I am unsure of where
to report possible problems to. Can anyone point me in to the right
