SharePoint 2010 Root Site logo is not changing

I have changed the root site and sub sites logo all the sub sites under this root site are working fine

all the layouts pages are rendering properly even in the root site itself.

One more interesting thing is if you open the sharpoint site in google chrome its not happening ,

only its happening in IE.

After i got the solution for this.

i opened the Welcome Webpart page in SharePoint Designer 2010.

I found that following tag is overloading the site Image then i removed it...

WebPartPages:TitleBarWebPart runat="server" AllowEdit="True" AllowConnect="True" ConnectionID="00000000-0000-0000-0000-000000000000" Title="Web Part Page Title Bar" IsIncluded="True" Dir="Default" IsVisible="True" AllowMinimize="False" ExportControlledProperties="True" ZoneID="TitleBar" ID="g_1b66ac5b_4a61_4a5b_90d3_dcca012fcdfa" HeaderTitle="Welcome" AllowClose="False" FrameState="Normal" ExportMode="All" AllowRemove="False" AllowHide="True" SuppressWebPartChrome="False" DetailLink="" ChromeType="None" HelpLink="" MissingAssembly="Cannot import this Web Part." PartImageSmall="" HelpMode="Modeless" FrameType="None" AllowZoneChange="True" PartOrder="2" Description="" PartImageLarge="" IsIncludedFilter="" __MarkupType="vsattributemarkup" __WebPartId="{1B66AC5B-4A61-4A5B-90D3-DCCA012FCDFA}" WebPart="true" Height="" Width="">

Now its rendering properly...
