I've had just a quick look at it and the problem could be in render.AlignResolution, but I'm not sure what it is exactly doing, see the doc string: 

"""!Sets display extents to even multiple of current
    resolution defined in WIND file from SW corner. This must be
    done manually as using the -a flag can produce incorrect
    extents.
    """

The differences in your screenshot are really big, I can see only small differences when I try to reproduce the problem myself. Maybe it could be related to projection?

Either it has been fixed by accident or it depends on some other settings. Can not reproduce it anymore with r49125
