OVROverlay Texture Issues on GearVR

Hi,
When I put the OVROverlay script on a quad and apply choose my texture, it displays correctly when testing with the Rift, however it displays incorrectly on GearVR. I get a repeated texture or clamping that extends beyond the bounds of the quad.
I'm using the quad as a reticle as a child of the CenterEyeAnchor offset in z-axis.

Here's a screengrab of what I'm getting in GearVR when using the gaze_cursor texture for testing.
