Just wanted to chime in here, but my Rezound also had the occasional chop to it. I use no animations, speed is at at the absolute max and I have 0 elasticity. A new update was released this past week, and it has made ALL the difference. In the what's new part it mentions one fix was for screen transition speed. Definitely noticeable. Throwing it out there.
My suggestion would be to give feedback to the developer to let them know that you're having an issue. After all, when an update gets pushed out that has bug fixes "for these select devices" they only knew about those bugs because someone reported it to them.
