I was using the latest Webkit Nightly when I noticed that http://www.apple.com/ipad/pompeii/ wasn't rendering correctly. The "iPad Apps They Used" sidebar on the right renders upside down and backwards, and the large picture and picture-nagivation interface which should be at the top of the web page renders upside down and at the bottom of the web page instead of the top. This is apparently a PowerPC-only problem. I had someone #webkit check it for me on Intel using a recent Webkit Nightly build, and he didn't see any problem. Using the Webkit Nightly builds, I've narrowed down the regression to be between r67568 (which renders correctly) and r67643 (which renders incorrectly). I hope someone can use git-bisect to further narrow down the regression to a specific revision.

I think this is a Leopard issue, rather than a PPC issue.

This is an interaction with the code added for bug 48401, so it's only apparent on pages over 2048px tall.

Previous comment should have referred to bug 27272, which resulted in r48401.

My Bug 45971 was resolved as duplicate of this one, but something introduced with r70098 is breaking things entirely and I don't know if it's unrelated or if this patch fixes anything. Using Youtube's HTML5 setting, videos no longer appear at all and the video thumbnails don't appear. Read my original bug for more details. The latest glitch started with r70098 and continues with r70284.
