Hi, From the nightly builds WebKit-r67080 you can reproduce this broken (semi) scrolling by doing the following: 1. Visit any webpage, http://www.google.ca/search?q=chromium 2. Press "END" 3. Press Arrow Up, or Page Up What is the expected output? - The page will scroll up. What do you see instead? - Does nothing, no scrolling event occurs.

I cannot reproduce this on Mac with r67113, probably Windows-only.

I can reproduce this. Strangely, pressing the down arrow after End will cause the page to scroll up to the top and then scroll down one arrow's worth.

If you use WebKit r6700 it working fine. While it doesn't work in r67022. http://trac.webkit.org/changeset/67001 seems suspicious. If you look at this changeset, http://trac.webkit.org/changeset/67401 you guys disable smooth scrolling.

Indeed, with smooth scrolling turned off the bug goes away.
