I have a tree panel with a single column of xtype 'treecolumn' and it has a renderer.
When I exapnd any node in IE8 browser(os:- windows 7), the content of the children node flashes/flickers first before it expands and then displays the children contents.
But this doesnt happen with Firefox/Chrome/Safari.
Any lead on this issue will be of great help.
Thanks guys for help
