Guys, I analysed stats of Adreno 330, which doesnt cause me eye strain and 430/530, which cause my eye strain even with Android 5, on wikipedia I found something interesting. They introduced feature called Vulkan (https://en.wikipedia.org/wiki/Vulkan_(API)). It id mostly used for 3D things, but can also be used for 2d. It is an API with loads of features. So it might be that with this API the developers gained loads of control on GPU, thus they added something which causes us all eye strain. Any thoughts?
