consumption problem (critical for labtop)

Hello everybody, I always have a window "ksysgard" in my session. I noticed something that looks like a bug: the system consumes "abnormally", but not always. I was not able to cause the problem for sure. I am relatively sure it's related to KMail. Once opened and closed KMail. The only window "KSysgard" is open. It's strange because while preparing this e-mail, I re-opened KMail and opened Kate. Ksysgard was hidden. Deciding to watch the "consumption" while writing in kate, I de-masked Ksysgard: After this simple operation, consumption is re-lowered to a "normal" level ... Comments on the attached picture: The vertical lines are spaced 60 seconds (1 sample per second) The horizontal lines are spaced 5% The left side (96% CPU load) represents the opening of the session, The following peaks represent the closure of all the windows and then opening and closing KMail Most of the picture represents this abnormal consumption On the left, back to "normal" situation. I place this mail "users" list, because I dont want to repport a minor bug, if I'm the only one to see that. To you to confirm or deny... System kubuntu 10.10-trinity-enterprise (86x_64) Good luck to everyone, Patrick
