Oculus S right eye's meshes vanish

Hi,

I'm running Unity 2019.2.5f1, HDRP, with Oculus Integration 1.40.

If I look at objects straight on, both screens show all my objects like it should. As soon as I start to turn my head left, meshes start to vanish when they get to the furthest part of the right eye's screen, like the're being occluded (shadows stay). Once I turn my head back to the right, they pop back on-screen and appear. The left eye does not do that. It does this in both the Play window and if I Build the game and run the .exe. This is with the OVRPlayerController prefab. If I run another scene without the OVR prefab, just use the default camera, it doesn't happen.

Is there a setting I'm missing?

Thanks.
