To reproduce:

1. Download and open attached "repro950654.zip" project.
2. Generate and add osig file to the project.
3. Build and run application on the device which supports GearVR.

Expected result: Application runs smoothly. Everything is rendered clearly.
Actual result: Objects in the scene (Cube, Cylinder, Capsule) constantly flicker.

Reproduced with: 2017.3.0b1, 2017.2.0b11, 2017.1.1p2, 5.6.3p3, 5.6.0f3.
Not-reproduced with: 5.6.0f2, 5.5.4p5.
Regression introduced in: 5.6.0f3.

Devices under test:

Reproduced with:
Samsung SM G950U*, OS:7.0, CPU:arm64-v8a, GPU:Adreno (TM) 540,
Build:samsung/dreamqltesq/dreamqltesq:7.0/NRD90M/G950USQU1AQC8:user/release-keys

Not reproduced with:
Google Pixel*, OS:8.0.0, CPU:arm64-v8a, GPU:Adreno (TM) 530,
Build:google/sailfish/sailfish:8.0.0/OPR3.170623.007/4286350:user/release-keys

Samsung SM G950F*, OS:7.0, CPU:arm64-v8a, GPU:Mali-G71,
Build:samsung/dreamltexx/dreamlte:7.0/NRD90M/G950FXXU1AQEB:user/release-keys

Notes: Did not reproduce neither on Cardboard nor on Daydream. Issue seems to be specific for Samsung Galaxy S8 devices with Adreno 540 GPU. Setting Anti aliasing to any lower value (4x for example) fixes the flickering.
