I am using tree in treepanel and treestore to show hierarchical records on UI for one of my application. When I add some no of records vertical scroll bar is appear. I am still adding records. When I do scroll bar up and down some records are invisible and process of hiding records is continue when I am scrolling up and down. When I do check or uncheck any one of record which is visible now, tree is refresh and I am getting all records back. Which component is responsible for this? How can I solve this problem ?

I was having the same issue with a grid and solved it by declaring:

bufferedRenderer: false

I.e.:

Ext.define('YourTree', {
   extend: 'Ext.tree.Panel',
   
   store: store,
   
   //other properties

   bufferedRenderer: false
});
