             Summary: Opening a modal popup above a datagrid with > 2000 items in it crashes the player
                 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.
