<http://trac.webkit.org/changeset/77101> caused the demo at http://people.mozilla.org/~roc/scrolling-boxes.html to be 43% slower than it was in r77100 and ~248% slower than it was in Safari 5.0.3. Note that this slowdown is in addition to the one tracked by <https://bugs.webkit.org/show_bug.cgi?id=56141> for the same demo.

Wayback Archive (2011 March - copy) - https://web.archive.org/web/20110313233153/http://people.mozilla.org/~roc/scrolling-boxes.html Chrome Canary 124 (with lots of tab and bunch of background activities) - 549ms Safari Technology Preview - 541ms Firefox Nightly 125 - 623ms ___ I think all browsers are close within margin, so it would be good to close it now. @Simon - any input?
