Latest Oculus App version: Seams in OVROverlay cubemaps

For our scene transitions, we enable the OVROverlay Cubemap before asynchronously loading. We received feedback that a user was seeing missing front & back faces and visible seams in the cubemap loading screen. We were not able to reproduce until one dev machine updated the Oculus App (1.22.0.520720) and the issue was reproducible in the Unity editor and in current and previous builds. Updating Oculus App on another dev machine produced the same results. The cubemap fails to completely overlay the render buffer, showing seams at all of the cube edges 100% of the time, and occasionally missing front and back faces. 

Is there any documentation of this problem that I have not found? Trying to narrow down SDK and engine versions which cause this issue. Using latest Unity 5.6. Updating to the latest Oculus Unity Utilities (1.22) results in a completely broken overlay (not visible at all).

Developing for both PC and Mobile, but the problem only occurs on Rift. Upgrading to Unity 2017 and OVR 1.21 did fix the issue. The cubemap is working fine on GearVR Unity 5.6 with OVR 1.14. Tested OVR 1.18 through 1.21 and could not get any Overlay rendering to work in Unity 5.6. 

We had already submitted a release candidate to the store when this issue began appearing so the Unity 2017 upgrade was a last resort! But for now this looks stable enough to release.
