WON'T FIX: this issue is Adreno drivers bug and it is no longer reproducible with Android 7.0. Issue only happens when the same vectorized matrix is being used in both vertex and fragment shader. Such case works correctly only if all 4 vectors of the matrix are being used within both vertex and fragment shaders. Non vectorized matrices work correctly. Resolving as "won't fix", because it's rare case and switching shaders generation to non vectorized matrices could potentially cause other issues.
