This brings up a good point, iDistort is not very intuitive. I find
using iTransform to be much more useful and quicker. It is a free
download off of Nukepedia.

This has always been a little tricky in Nuke. Straight out of the box iDistort
really doesn't do
a displacement distort like most people would expect. Instead it tends to
translate/offset pixels in
x and Y. it's more involved if you want something that looks like a a true
displacement map to fake
things like ripple glass, heat distortion or lens distortion.
Unfortunately I haven't done this in a while and can't remember exactly how we
solved this issue.
That's not a particularly helpful answer, but at least it affirms your
suspicion that something
isn't working as expected.
Let me see if I can find one of my old scripts.
