100% cpu usage whenever Autodraw is used

[WhiteNoise]

widget->Autodraw seems to be consuming massive amounts of CPU on my iPad 2. If I run instead with a timer running at a lower framerate, CPU usage is better, but still higher than I think it should be.

would you happen to have instruments or shark sessions that show the problem? Also an XML dump of your widget tree may help a bit.
