Not reproduced with :

Sony D6603 (Xperia Z3), OS:6.0.1, CPU:armeabi-v7a, GPU:Adreno (TM) 330, Build:Sony/D6603/D6603:5.1.1/23.4.A.1.264/2418263178:user/release-keys

Notes: Could not test on earlier versions because Cardboard was added in 5.6. Reproduces only on Mali GPUs. In Scripts folder there is VRcontroller.cs script where render scale is controlled. If both lines with VRSettings.renderScale are commented or deleted project works without any issues.
