Description Ricardo 2009-08-16 19:37:16 UTC

Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    SuSE RPMs

The Xorg process is about 70% and the plasma-desktop is about 28%
If i remove the traybar, it gets normal, if i add it, this load happen again (i can reproduce it everytime)

Comment 1 FiNeX 2009-08-16 21:09:59 UTC

Do you mean "system tray" with "traybar"?

Comment 2 Ricardo 2009-08-16 21:53:02 UTC

yes, the plasmoid that shows icons  (reworked on 4.3)

Comment 3 Dario Andres 2009-08-16 22:47:15 UTC

- What icons do you have in the tray ?
- Do you do some file operations that would show the notification progress ?
- Do you use some application that would show a lot of notifications ?
Thanks

Comment 4 Ricardo 2009-08-16 23:06:03 UTC

Previously i had amarok, akregator, kwallet, korganizer, dropbox, opensuse updater applet, but i stopped all those applications, and the load was still there. The dbus process was at 2-3%
No file operations were done at that time
I had no opened applications (nor nepomuk, nor strigi)

If required, I can install a vnc server or something so you can see the problem by yourself

Comment 5 Lukas Dolezal 2009-08-17 11:41:17 UTC

I can confirm that, but only if I have some icons categories (system services, etc.) hidden. If I have all icons shown, cpu usage is in normal. It may be connected with my other bug #203164.

Comment 7 Ricardo 2009-08-17 11:56:35 UTC

@Lukas you are complete right, i had one category hidden (hardware). At least now i can use it again

Comment 8 Dario Andres 2009-08-17 15:36:53 UTC

Thanks for the data. Updating the title. Regards

Comment 9 Beat Wolf 2009-08-25 11:35:25 UTC

Comment 11 Dario Andres 2009-09-16 14:56:42 UTC

To all the people experiencing this bug: besides having a Icon Categories marked as hidden (checkbox unchecked), did you had the "Application notification" setting from "Popup notices" also disabled ?  (That is the case of bug 207177, which I could also reproduce on 4.4)..
Thanks

I did had it enabled as you can watch on my previous video attachment (https://bugs.kde.org/attachment.cgi?id=36210).

When I disable it (Application notification), nothing is changed.

Comment 13 Dario Andres 2009-12-14 20:50:22 UTC

Yes, it seems that the Application notification settings is not relevant.
Merging with bug 207177 Thanks
