Subject: [flexcoders] Bug in Flex scrolling?





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
