Game Scene problems when using GvrViewerMain

I’ve just started developing an app for google cardboard, set up google vr 1.20 on unity 2017.1.0f3.
I’ve added the GvrViewerMain and whenever I try to run it the emulator I get the following problem

The settings are default and I haven’t tinkered with them.
As it’s only an emulator it looks fine on the phone itself.

Should have googled more before posting this, it has been solved and the following solution can be found here: Wrong stereo rendering in Unity 5.6 game viewer · Issue #451 · googlevr/gvr-unity-sdk · GitHub
