Got a solution for this. If you press F12 after opening your dashboard in IE, you will get the developer tools and you can see Document Mode. Change that to IE 8 standards - for me, after changing this, the dashboard opens properly.
The issue is - the dashboard was opening in Quirks mode by default and with that document mode the page is not rendering properly.
The DOCTYPE is send by the app i.e. QV Accesspoint. So if you can help me where to set the DOCTYPE in QV server so that the document mode will be set automatically.
