Game Name?
Cubivore: Survival of the Fittest

Game ID?
GCVEEB

What's the problem? Describe what went wrong in few words.
When playing Cubivore, the game does not fill the screen, either in full screen or in windowed modes.
I've used OpenGL, both Direct3D 9 and 11, and Software rendering modes. No combination of graphics settings seems to resolve this.
Aside from this issue, the game runs flawlessly.

What did you expect to happen instead?
I expected the game to fill the window, rather than a fraction of it.

What steps will reproduce the problem?
1.Open and run Cubivore

Which versions of Dolphin did you test on?
4.0-2917

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
The wiki describes r7420 as working, but I cannot test for myself.
