UI Accordion Doesn't Redraw Properly in IE

UI Accordion Doesn't Redraw Properly in IE

I've attached a screenshot of this problem I've been wrestling with. Searching the forum and Google hasn't turned anything up, but maybe I am not referring to the problem correctly.

When I use the UI Accordion with a definition list (where the DDs contain might contain both text and images, if that matters) the page loads fine, but after clicking on a DT to expand it, some DTs are redrawn after moving down on top of other DTs below them. Hovering over the misplaced DTs a few times will pop them into the right spot. 

Relatedly, in this same page, if I maximize or restore the browser window after page load, the elements will jump out of their places from the center of the page to the left edge relative to where they first loaded. Refreshing will pop them back.

These seem to be redraw issues, but I don't know how to correct them. I've tried switching from 1.7.2 to 1.8 today but it happens with both versions. Could this be related to how jQuery interacts with IE and scrollbars?
