Had the same problem and noticed when I looked at the system tray settings under "entries" there were lots of 'phantom' entries which stops you resizing it down to the real size.
I finally found the answer here: http://forum.kde.org/viewtopic.php?f=67&t=99419 In summary run the following command... killall kded4 && kded4 & It clears out all the entries and allows it to be resized. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/944695 Title: Removing and readding the system tray in KDE doubles its size each time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/944695/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
