State of Gear VR

Perhaps this is my ignorance (I’m a rookie developer) but I’ve been creating my first GearVR project and I’ve experiences a (I assume bug) where sometimes the left eye won’t render some of the textures, for example in my left eye the floor will go black or some objects will turn completely black. Sometimes I’ll include say a static mesh that is set to ‘movable’ and the entire game will be dark on startup, until I turn around and look at the object that I’ve just added, then I can see everything. It doesn’t happen with the Oculus or on PC. Is this a known issue? Or have I just done something crazy?
