My friend Axel Jensen wrote a blog about this including a fix for it. It has to do with the item renderers being re-used and re-populated by the list control. His example is a tileList with images pulled from a server. The blog is here: http://www.axelscript.com/2009/03/30/itemrenderer-tilelist-issues/ and the example is here: http://www.axelscript.com/2009/03/30/itemrenderer-tilelist-issues/
Hope it helps!

Hi everybody, Very often, when I use the container/list/datagrid with scrolling, scrolling when dragging scrolling pad causes incorrect rendering of the controls that are being scrolled. If I use the up/down button (the scroll speed is slow), the rendering comes out OK. Whenever I use the scroll pad and scroll very slow, the rendering is also fine. Only when I scroll fast, the rendering is very often incorrect. Also, if i hover over combobox controls which are not rendered correctly, they redraw themselves in correct positions. Is this a bug in Flex or is this due to incorrect configuration of controls? How can this be fixed? Your help is greatly appreciated! Many thanks Denis No virus found in this incoming message.
