Check how do you set data, is it binding, dataChange event or overriden set data()
There is also a "trick" where you can speed up DataGrid scrolling, I can't remember exact code, it is something like: datagrid.scroller.verticalScrollbar.addEventListener(Event.CHANGE.... then in handler you force update with: event.currentTarget.viewport.validateNow(); Try to create smallest possible case where you have problem and post it here. -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Bad-Datagrid-scrolling-performance-on-Yoga3-core-i5-geforce-940M-tp12047p12593.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
