Be sure to use deferred rendering and set it on camera. Forward can give you a problems, but there is really no need to use it, as with VR panorama you can get nice antialiasing in deferred, and overall a better quality rendering with many shadows. If you are using forward rendering this should correct your problems. If you are using already deferred rendering, please attach a screenshot of your scene hierarchy (part with VR panorama camera) and VR camera attached scripts. Latest version of VR Panorama doesn't use depth buffer, because this gives you faster rendering and less VRAM usage. I will probably expose this value in a next version as an option, that will also support multiple layer rendering.
