UI issue on Unity Daydream

Question

As you can see in the attached image, the game view in my Unity project has some issues. It looks like it is duplicating the view in increasing smaller slivers of the main view. Any fix for this?

I'm running Unity 5.6.0 beta with the Daydream VR asset.

Answer 1

This will be fixed in the next update. In the meantime, please use the workaround posted below:

This looks to be an issue introduced in 5.6. I'm not sure if this was an intended change in Unity or a regression. Until we have a resolution the following changes will correct this for users of the SDK.
