Comment 60 for bug 1502556

I can confirm the huge RAM usage in (K)ubuntu 15.04, after updating from 14.10.

I was using two panels (one bottom, one top) in the first screen of a dual screen setup. I had some application icons, show desktop, trash icon, the systray and the clock in the top panel and the taskbar in the bottom one. Backgrounds set to black color in both screens. Systray elements: kmix, networkmanager, klipper, notifications and updates. No desktop widgets.

I can't give more info because after finding KDE was using 2,7GB of my 4GB RAM I immediatelly went back to the 14.10 installation backup so I could start working. Not updating until Javascript is grounded I guess.
