How to get rid of unwanted scrollbars in an SSRS reports within an Iframe and increased Windows display size?

Question

We run an web-app with built-in SSRS reports, which are integrated via an Iframe.

A user has set her display percentage to 150% in Windows 7. (Control Panel > Appearance and Personalization > Display).

She is displaying the webpage with the report in Firefox and she has to scroll horizontally and vertically within the Iframe to view the whole report.

I managed to get some screenshots

• no scrollbars in Firefox with a display percentage set to 100% set in Windows 7 http://screencast.com/t/MGM3MmQzOTgt

• no scrollbars in IE8 (with display 150% set in Windows 7) http://screencast.com/t/ZjE3NGVj

• scrollbars in Firefox with a display percentage set to 150% set in Windows 7 http://screencast.com/t/ZmI1Yjkz

Somehow Iframe and SSRS don't seem to work together well, but how to solve this?
