Android/HTC One screen anomaly? I was wondering what has happened to my HTC One. Is it a hardware issue or an Android/software issue?

The screen has usually moved half way between when I enter and exit any app. Since a picture speaks a thousand words:



Notice in the picture/screenshot from my phone, that I have a partial view of both screens. That is strange and I am not sure what the problem is.
It most certainly is not a hardware related issue.
I would begin by rebooting the device.
