I can only seem to reproduce this in Chrome. When a document is long enough to require a scrollbar, scrolling will put horizontal lines over the newly viewable part of the document. It seems to be related to the <td> which has a border that the iframe is in. If I change the color of the border-bottom the lines output over the document change with it. I thought removing the border would resolve the issue, but it puts white lines over instead of black, transparent border has the same effect. I can't seem to reproduce this in Chrome with regular iframes or any of the official demonstrations on this website.
I have tried changing ContentAreaMode to DIV and although the lines do not appear with this it causes other issues so isn't a viable solution.
Any help anyone has would be much appreciated.
