I made a joke about gamma values in p.b.i, but since you are getting your height
values from an image, I might have actually been close. The valley floor
is flatter, the peaks are sharper, and I would bet money that the new beta is
doing gamma conversion on the height values when reading the image and older
versions didn't. The image looks a lot like what I did years ago to get a flat
valley floor: square the height values, and typical gamma values are in the 1.8
to 2.2 range.
The quick workaround would be to gamma correct your height field image with a
value of 0.45 or 0.5 before letting the new beta read it in, reversing the new
bug.
