Description

Steps to reproduce:
1. Create a flex application with wmode set to transparent or opaque.
2. Create a VBox and set to the full width of the application.
3. Create a HBox inside the VBox and set width to the full width of the VBox.
4. Create a component that is an HBox with a border and put an image inside it, left aligned. Add several of these controls to the 1st HBox so that it expands beyond the width of the application and the VBox shows a scroll bar (recommend atleast 2x the width of the app).
5. Scroll with the VBox scroll bar.

Actual Results:
In Internet explorer you get rendering issues (see IE8.jpg) as if the application is not refereshing properly. Items will refresh properly when they gain focus (my application uses object handles to select and enlarge the boxes).

Expected Results:
Items should render normally as in Chrome.jpg (taken in google chrome)

Workaround (if any):
None.
