Package: xserver-xorg
Version: 1:7.3+10
Xorg is eating lot of CPU (up to 100%) on trivial tasks such as :
- scrolling with Shift+PageDown in a big openoffice calc spreadsheet
- resizing the default Xfce Terminal
- scrolling in big web pages with iceweasel
- switching for tab to tab with iceweasel
I do not use compiz, fusion, or anything else like that.
My deskop manager is Xfce 4.4.2.1
After having found this link :
http://lorenzod8n.wordpress.com/2007/12/23/xorg-73-in-sid-harmful/
I tried to downgrade xserver-xorg (and only xserver-xorg) to Xorg
1:7.3+7, determining it was the right version to test by using the
date on this blog + http://snapshot.debian.net/
Everything is fast again, I can re-use openoffice and iceweasel normally.
Try adding
Option "AccelMethod" "XAA"
to the device section of your xorg.conf

Interesting behaviours :
- 7.3+10 : fast on laptop screen (1024x768)
- 7.3+10 : a cpu glutton when switching on external screen (1920x1200)
- 7.3+10 + XAA option : fast, but I cannot use xv for my videos, only x11
So EXA (default choice) is better for xv, I will stay on 7.3+7 until
problem is solved (maybe GLX_EXT_texture_from_pixmap, maybe not)
