I have a problem on my desktop PC that i'm trying to solve for last 10 hours.
When playing videos on Youtube for example, Xorg process uses all available CPU %. While Firefox usage goes up to 45%. That renders Firefox unresponsive and video is barely played at 10 FPS. Thing is, if i scroll down so that the video played isn't visible, Xorg CPU usage goes back to normal.
This is the configuration of the PC i'm having this problem on:
I tried using different Flash players and plugins for Mozilla, but with no improvements.

Currently i'm using:
I've tried disabling Icedtea plugin in Firefox just to be sure it's not causing a conflict.
ii adobe-flashplugin 10.0.45.2-1lucid1 Adobe Flash Player plugin version 10
to /etc/adobe/mms.cfg but with no luck.
I know this is an old computer, but i have a laptop with similar hardware: 1.4 Celeron and ATI Radeon Xpress 200M chip which uses the same graphic driver; and Xorg never passes 7% CPU and mozilla is around 30% when watching the same video on youtube.
Also i've tried disabling desktop effects, but that didn't help either. Xorg log doesn't show anything out of order.
So after 10 hrs of screwing around with this problem i'm realy out of ideas. Any help would be appreciated.
