dash not fullscreen in virtaul machine with vmvga backend for kvm machines

[Lyn Perrine]

Install ubuntu 15.04 in a virtaul machine with kvm using virt manager and vmvga graphics backend. Then type display in the dash and give the virtual machine a 1440 x 900 resolution and apply it. Then press the super key to open the dash and notice that it only covers part of the screen when I could get more search results in the dash if it was fullscreen like in 14.04.

I expected a full screen dash. Instead the dash only covered part of the screen.
