------- Additional Comments From alessandrosturniolo yahoo it  2007-12-05 21:31 \
------- I've done some other test. This is what I've founded:

The problem is introduced by kwin 3.5.6. On my Gentoo I've forced the system to \
install kwin 3.5.5 (with kde 3.5.7), and the problem is disappeared. With kwin 3.5.6 \
the problem come back.

I've tried to downgrade only superkaramba, to previous versions, but with no success.

The problem is most frequent with applet with fast update time (1 second or less).

The problem is observable also without a screen saver. After few minutes (3-4) the \
CPU usage begins to grow, and after 10 minutes the PC is unusable, because Xorg (a \
process that running with root privileges) use 100% of CPU. My system is a single CPU \
Athlon XP 3000 (a 32bit single core CPU). It's possible that with multi CPU, or a \
recent PC, the system stay usable.

I don't know if is a bug of Xorg, superkaramba or kwin, but I know that without kwin, \
or with kwin <= 3.5.5, the problem disappear.

To reproduce this bug, use kwin >= 3.5.6, superkaramba and a lot of applet (clocks, \
system monitors, and some other with frequent updates), then leave your system, and \
come back after 30 minutes.

Thank you.
