Description

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.
