> Key: FLEX-34444
> URL: https://issues.apache.org/jira/browse/FLEX-34444
> Project: Apache Flex
> Issue Type: Bug
> Components: PopUp Manager, Spark: DataGrid
> Affects Versions: Apache Flex 4.12.1
> Environment: windows 7, Internet Explorer 11
> Reporter: Josh Weinberg
> Attachments: TestGrid.fxp
>
>
> When any type of modal popup or alert is opened over a Spark Datagrid which
> has more than ~2000 items in its dataprovider the default blur effect on the
> modal popup causes a player crash.
> Run attached example application.
> \\
> \\
> * Initially, open the popup (I used an Alert but any modal popup will cause
> this).
> * Then add items to the data provider and open the popup again.
> * After ~2000 items are in the data provider opening the popup will crash the
> player.
> * If you turn off the blur effect using the modalTransparencyBlur style then
> it will not crash.
> Interestingly if you add ~15000 items the popup turns off the blur itself and
> it will stop crashing.
