See upcoming testcase, you need to download the testcase locally because of the use of enhanced privileges. To reproduce the bug: - Click on the 'set printpreview on iframe' button. - Click on the 'undo printpreview on iframe' button. After that the contents of the iframe bleeds out of the iframe. This seems a bit similar to bug 331809. This also regression with the landing of the frame display lists patch (bug 317375).

Also the scrollbar extends too far vertically after following the steps to reproduce.

I guess this will probably be fixed by bug 331809.

I can't reproduce this bug on Linux (there's no bleeding outside the iframe), but the testcase still doesn't render correctly in print preview mode. I think it's a different bug so I spawned it off as bug 404253.

Ok, no problem anymore, using: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b2pre) Gecko/2007111905 Minefield/3.0b2pre So I think this was fixed by bug 331809.
