This is because the object is exactly centered at (320.5, 239.5), which is
the center of pixel (320, 239). So it will look symmetrical, but it's
centered around the wrong place.

In fact, the 3.5 beta 11 image is also centered at (320.5, 239.5). Did you
set #version to 3.1? That would disable the half-pixel bug fix.
