jquery-ui sortable “overlapping” flickering issue

jquery-ui sortable “overlapping” flickering issue

Hi, everybody!
I'm a frequent jQuery user and has used it for a year or so, but there's one problem which I can't figure out how to deal with except by overriding some sortable-jquertui functions which I would not like to do. Anywho I originally posted on StackOverflow but feel like I need to ask for help from "the source" itself. I'm sorry for using a link to my actual question but it's a pretty heavy post which makes it seem stupid not to just refer to it.

The link:

If any of you don't like me referring to a StackOverflow post I am of course willing to repost the whole thing here. :)

Thx!
