Unity 5.3.1p3 - Viewports on Render Textures are warped when Virtual Reality Supported is enabled.
I have a panorama set up in my scene (similar to the answer here). I have an issue where my viewports (set up with {X, Y, W, H} values of {0, 0, 0.16, 1} each). When I run Unity normally, everything looks fine, the panorama is good. When I run with Virtual Reality Supported, the values don't change, but the render textures look way off. This is evident on other normal render textures I have set up in my scene as well, who haven't had their viewport values altered.
I could write a script that could act as a stop-gap, switching values for the viewport between one set of values when VR is enabled and another when it isn't, but this seems hack-ish to me. What's the best solution to this? Is this a bug with Unity, or should I change my method of creating render textures?
