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.
