Android Game has geometry flickering on PowerVR device

One of my users reported that my game build is flickering on their device.

The device is LG K50S, which uses the Android_PowerVR_GE8xxx device profile.

The device profiles have the default values, I didn’t tinker anything with it yet. The renderer is OpenGL ES 3.1.

Video showing this behavior:

I tried turning off/on mobile hdr, no change.

Did you ever found out how to fix this?
