<hr> elements on a page produces small artefacts when they're being scrolled
into view. Slowly scoll - more artefacts. However they're only appear for <hr>
elements without noshadow attribute. Testcase and screenshot of a problem are
provided. I can also note, that this problem was not available in previous
build, i've used: 2003020408, so it appears somewhere in past 3 months.

trunk build 2003051708 on Win2k

With your testcase provided, I do not see this problem.
Have you enabled or disabled smooth scrolling?
