    Open tree/locking-buffer-rendered-treegrid.html

    Expand a few parent nodes and scroll down, note row height not lining up (notice the row hover over els).Screen Shot 2013-01-14 at 11.11.33 AM.jpg

    Looks like that may have been fixed. I can repro in 4.2.0.265 but not in our latest code.

    This is still open, just checked using latest nightlies.

    Test case:

    Code:
    Ext.Loader.setConfig({enabled: true});
    
    Ext.Loader.setPath('Ext.ux', '../ux/');
    Ext.require([
        'Ext.grid.*',
        'Ext.data.*',
        'Ext.util.*',
        'Ext.grid.plugin.BufferedRenderer'
    ]);
    
    Ext.define('Employee', {
        extend: 'Ext.data.Model',
        fields: [
           {name: 'rating', type: 'int'},
           {name: 'salary', type: 'float'},
           {name: 'name'}
        ]
    });
    
    Ext.onReady(function(){
        /**

    Default Is this fixed?

    We are still seeing this problem in 4.2.2.1144. Should it have been fixed in that release?
