Comment 45 for bug 1502556

I installed Fedora 22 on a virtualbox without 3d acceleration.
I am experimenting huge processor load under kde -> plasmashell using 120% of processor on 2 procs.
After trying a little bit, I was able to get the processor load back to normal by removing all plasma widgets on my desktop.
Once I add a plasma widget, the processor load rise to 120 % (tested with just an analog clock, just a notes, and just a processor load watch).
