Jumping icons in dock when choosing a window

[Ahmad Mohammad Issa]

I'm running the live USB on my laptop, (Acer Aspire v3-571g, i5 CPU and intel hd 4000/nVidia 640M GPU).
I opened midori and when the dock lost focus the Midori icon and the "Install Elementary OS" icon started jumping - they were the only icons I had pressed.

It would be a much better idea to install eOS in virtualbox in order to report bugs, as some bugs may have already been fixed (the live USB can't update).

To me this just sounds like performance issues due to slow IO (you're running from a CD after all). There's nothing we can really do about that. We recommend booting from USB.
