Unfortunately: I used a LiveCD 2006.0 and it worked fine. I have an up-to-date (and revdep-rebuilt) stable Gentoo on ThinkPad T42. When I'm changing the document zoom level (especially with the toolbar buttons) or switching into fullscreen mode it takes up to ten seconds (I looks like freezing the whole GNOME)! I really can't figure out what's involved...

With what kind of documents? What X driver are you using? Thanks
(In reply to comment #1) > With what kind of documents? What X driver are you using? All pdf documents. I have an ATI Radeon 7500. I'm using the open source ati drivers -- there are no binary ATI drivers for this card -- it's to old (although those notebooks were sold by Lenovo/IBM less than 3 years ago). I don't have such problems with other applications.
Your only shot here is to use a profiling tool such as oprofile or sysprof to figure out which piece of the chain is slowing everything down. You can run these tools to first figure out which application is hogging the CPU. Once you've done that, you'll have to follow http://www.gentoo.org/proj/en/qa/backtraces.xml for better results. However may I first suggest you disable EXA on your graphics driver if it is enabled, or enable it if it's not? Thanks

I can attach a full strace log if necessary. What is an EXA?
strace is mostly useless in this. We need to figure out where the CPU time is spent. System calls are somewhat irrelevant (at least for now). As for EXA, it's a graphical acceleration architecture provided by the X server. Could you please attach your xorg.conf and /var/log/Xorg.0.log here? Thanks

From Xorg.0.log: (==) RADEON(0): Using XAA acceleration architecture That's not very good. But then again, you're using a stable X stack... Try enabling EXA by putting : Option "AccelMethod" "EXA" into your "Device" section. Thanks
It's still not perfect but *much* better, let's say: acceptable. I'm just wondering why I had this problem only with the Evince. Other appliactions that are part of the GNOME Dekstop Environment used to work fine.
Because evince stresses cairo (and thus the graphics pipeline) more than any other application on a standard Gnome desktop. Closing invalid. Thanks for the quick follow up.
