Lines issue sounds like https://bugzilla.mozilla.org/show_bug.cgi?id=281953

Could you make a much smaller testcase that still shows the problem and is
*easy* to reproduce?

I only see some weird little border lines by the way in a recent nightly. The
movement of content is no longer happening. So this either is a duplicate of bug
281953 or a WORKSFORME I guess.

Content displacement fixed in my nightly (Mozilla/5.0 (Windows; U; Windows NT

...

So I guess this is a dupe :S
