Created attachment 90626 [details]
A recreation of the bug.

When a large fixed serif element is italicized, it can extend past its own redraw region. To recreate, view the attachment or create a large (~72px) italicized serif element. I've recreated it with Times New Roman and Georgia.

In the attachment, look at the bottom-left corner of the 'I'. It is more prominent when scrolling horizontally but does exist when scrolling vertically.

I was going to say that this is a duplicate of bug 6274, and then found that it seems to be a regression. I can reproduce with ToT, but not with Safari 5.0.5 on Mac OS X 10.6.6.

Do you know if this affects any web sites?

I would still call it a duplicate of that bug, even though in this specific case the problem was masked by something else in Safari 5.0.5.

I am not able to reproduce this bug while scrolling horizontally using WebKit ToT (263713@main) where 'I' shits on bottom-left corner.

If it is something reproducible for others, please mark this accordingly.

Although Comment 02 suggests that it might be duplicate of bug 6274, so marking this duplicate also works IMO.
