Try loading http://fourfour.typepad.com/fourfour/2011/02/judge-judy-gifs.html and scrolling down. The images animate slowly and the page stutters while scrolling. Firefox renders the page smoothly.

Chrome 11/Win doesn't seem to do too badly here; once the images load, page scrolling perf is noticeably but not radically decreased. I imagine that the current work to move scrolling to the GPU will help that.

One issue here is that builds of WebKit using ImageIO for image decoding had an ineffectual fix for bug 26455. That’s now fixed by bug 54919. I think leaving this bug to track any scrolling performance issues seems sensible.
