We built an animated banner with Sencha Animator 1.3 but it has a scrolling issue on mobile pages and even on a plain webpage with absolute zero javascript.

Whenever you scroll on a mobile page or a desktop page, the Sencha animated HTML starts showing weird display issues. It is fine as long as you don't scroll on the mobile/website page though.

Any thoughts on why this is happening?
See attached screen shot

View banner on ipad or tablet, scroll down on page to see issues.
