"Binary package hint: evince

I'm using gutsy, and I have evince 0.9.1-0ubuntu1.
I notice a very hi cpu usage in this version of evince.
When scrolling, and when moving a small window (for instance a terminal) over
evince with a open pdf.
This makes evince bad because it is too slow to use!

Yes it happens with all pdfs!
here's an example.
If a sidebar is the bar that opens when pressing F9, no. But it happens also
when it is enabled.
It happens in al "view" modes: fullscreen, continuous, dual...

Could it be a graphic driver error?

P.s. I have a mobility radeon 9700. I use the default driver"
