Vaadin components disapear in Chrome when using scrollbar.

On BlackBeltFactory.com home page, Chrome users see the right columns disappear when they use the browser scroll bar to scroll down in the page. Then they reappear according to the scroll bar position. Only in Chrome. I use Chrome 4.1.249.1064, but other users have reported the problem on our forum.

I was not sure if it was a problem specific to our application or more general with Chrome-GWT-Vaadin, until ... I used your add-on Vaadin application to upload a plugin: Gotcha!!

All components are there: http://screencast.com/t/MTA0MzY5YTct

Scroll up -> some components missing: http://screencast.com/t/YjZiZWRiMzk

It is a known problem?

Thanks.
John.

This is a known regression in Chrome:

This can be reproduced without Vaadin and did not occur in Chrome 3. Please add links to your screencast to above google code ticket to give more pressure to Google to fix this critical regression in Chrome.
