Hi,
there was a bug on lock screen before the update and it is still there. I thought Sony might have not been noticed it because it is really a small bug so I wanted to give information. If you use draw pattern when you touch left or right bottom corner for a while it reflects as you touch widget. Or if you slide top to down at right or left corner it enlarges the widget.
Edit: I have take some screen shots:
