roundedcorners postback flicker

Hey guys.

I have a formview within a panel. Everything works great and when adding a post the screen wont flicker and the post is viewable in the panel immediately.

I recently tried to apply an ajax roundedcorners tool on the panel and it works but the screen flickers at every postback. Is there a way around this?

Could you post some sample code that reproduces the issue? I tried it out but perhaps I am missing something.
