1) Don't cross post. 2) Install something more recent that 4.6 (e.g. 4.9) and you will find that partitions and filesystems will be aligned on 4K boundaries.
3) If you can, without trying hard, end up with misaligned partitions on a fresh 4.9 install then please detail the steps you followed and I for one would be very interested. ....
