Gaze Pointer (Gvr reticle) seems double

"The Reticle A reticle can help to indicate the center of the user’s vision. The style of the reticle could be a simple dot, or perhaps a crosshair, depending on your project. In traditional 3D games a reticle will often be set at a fixed point in space; often the center of the screen. Positioning a reticle in VR is more complex: As a user looks around a VR environment, the eyes will converge on objects closer to the camera. If the reticle is in a fixed position, then the user will see double: You can simulate this by holding a finger in front of your eyes and focusing on objects closer and further away - if you focus on your finger, the background will double, and vice-versa. This is known as voluntary Diplopia. To avoid the user seeing two reticles as they look around the environment and focus on objects at various distances, we need to position the reticle at the same point in 3D space as the surface of the object they’re currently looking at. Simply positioning the reticle at that point in space will mean that the reticle will be tiny at large distances, and large when up close. To ensure the reticle stays the same size regardless of distance, we need to scale it with distance to the camera. To illustrate this, here are some examples of the reticle at different distances and scales, taken from the Examples/Reticle scene." https://unity3d.com/learn/tutorials/topics/virtual-reality/interaction-vr
