Public bug reported:
Computer is an atom 320 with 512MB RAM. Ubuntu 8.10. While not a
powerhorse, I'm not sure this is quite normal.
Setup is an idle xubuntu desktop with the CPU, Network and Memory
taskbar applets. These applets display usage by means of vertical
progress bars.
If in the xfce theme selector I choose either Human or HumanClearlooks
themes, Xorg CPU goes, according to top, to 30-50%. I note that these
themes animate progress bars continually (slanted darker bars that
move), but I don't know if this is actually related.
Chosing other theme (for example the default one), CPU drops to 1-2%.
Having compositor enabled or not does not make a noticeable difference
(perhaps a 1%).
Not entirely sure if this is a bug, but that large usage when idle, even
with this processor, seems suspicious to me.
