Alex Harui commented on FLEX-34331:
-----------------------------------
Can you attach the code for the renderer? If you make the children of the
renderer always invisible, (don't make the renderer.visible=false as that will
get reset by the ADG) does the problem go away? That will narrow down the
issue to the children of the renderer.

> Key: FLEX-34331
> URL: https://issues.apache.org/jira/browse/FLEX-34331
> Project: Apache Flex
> Issue Type: Bug
> Affects Versions: Adobe Flex SDK 3.5 (Release)
> Environment: OS : windows7
> Navigator : Firefox
> Flash version : WIN 12.0.0.70 (Adobe Windows)
> SDK : 3.5.0
> Reporter: bsb-tn
> Priority: Critical
> Attachments: screenshot-1.jpg, screenshot-2.jpg, screenshot-3.jpg

>
> We are displaying data in a grid using flex, one of displayed columns is a
> url column that shows a label behind which there is a link where you are
> redirected once clicking on the label.
> We are using a UrlColumnItemRenderer which is a class extending
> mx.controls.LinkButton, there we handle the data, clickHandler methods.
> The column is of type
> mx.controls.advancedDataGridClasses.AdvancedDataGridColumn and has as
> ItemRenderer UrlColumnItemRenderer.
> The url column we are displaying has a bold font, and we managed to change it
> to make it underlined with a normal fontWeight but still getting the same
> issue.
> The issue we are encountering is not systematically occurring, It just
> happens when we resize the window many times after many tries in a quite
> "random way" (we reduce then increase the window size, switching to full
> screen mode then recovering the old mode many times).
> Once issue occurs, we are getting that strange spot that remains at the same
> place (on the screen) even when we scroll the view up and down (as if It
> became independent from the view itself).
> If you want more clarifications or details, please let us know.
