Using the same ROM myself, however I ran into screen alignment issues once in awhile previously.
What I found that was partially causing the issue... if you slide open the keyboard and use the keys to get back to the align screen control panel you need to make sure you're doing it with the proper hand for landscape alignment. (I guess the tech who coded that control panel was left handed....) As the control defaults to left handed alignment. So it compensates the wrong way if you are right handed thus throwing off the alignment yet again.
Simple mistake after a couple times I noticed it
