Geometry Shader doesn't work well on Oculus Quest

I'm developing a VR content on the Oculus Quest. My question is that whether I can use geometry shader to the Oculus Quest?

I tried to use a geometry shader on a new project. It worked well. But if I use it on my progress project, it doesn't work well. An Oculus Quest will render broken result like much darkness.

If an object attached a material that use the shader is in front of an oculus camera, the result view is so darkness. But if the object out of the camera view, the result view will get correct rendering.

I found a problem out that is "OVR Manager" script is wrong. If I disable the script, the result is going well.(Of cause, all of headset pose are disabled)

What happened? How to resolve it?

Does anyone know about reason?
