Hi Qt developers,

My QML code shown as below:

ListView {
     model: xmlModel
     anchors.fill: parent
     delegate: Item {
         width: 340; height: 95

         Image { source: "../images/3index-content-bg.png" }
}

I use XmlListModel to parse a XML such as 
http://planet.qt-project.org/rss20.xml

Then I use delegate Image to render the Item`s background, if scroll the 
listview up/downwards very quickly, when stop, the Item`s background 
Images overlapped just like

My mesa-10.2.2-1.x86_64                            an open-source 
implementation of the OpenGL specification

Please someone give me some advice, thanks a lot!

PS: if scroll the listview very slowly, then it is ok, but I can not ask 
customers to scroll it slowly ;P
