I'm having two issues with Warp Stabilizer. Has anyone else run into this?
-It seems to interpret rack focus as a zoom so it over corrects as the scene comes into focus. There's bit of a scale "bounce" as this happens.
-It seems almost impossible to eliminate rolling shutter with telephoto shots. If anything, Warp Stabilize only amplifies the jello look. (even with DetailedAnalysis & Enhanced Reduction On)

Warp Stabilizer can't track out-of-focus or heavily-motionblurred areas. It does its best based on the other parts of the image, but if the untrackable portion is large you'll get results like yours. If you're willing to put up with less smoothness, sometimes you can save the shot by dialing Smoothness down from 50% to 5% or 1%. The worst shakes are still removed, and the remaining movement can cover up other problems.

I wouldn't expect telephoto to make it worse per se (better, actually, because of less parallax), but if your shot has a lot of depth and thus corresponding out-of-focus areas when zoomed in, that does make it worse as noted above.
