Full screen from command line

[goodjaerb]

I just built Dolphin from source on Ubuntu 15.10 desktop. I configured to run fullscreen so that I could launch from a frontend however when i launch with the command

Code:

dolphin-emu -e <iso> -b

the Dolphin window pops up on top and the game starts playing below it, and the Ubuntu launcher is also still visible. I can click the game screen to bring it to front, but it should start on top. Has anyone seen this or know if I'm doing something wrong to cause this.
