--- Comment #3 from Myles C. Maxfield <mmaxfield at apple.com> ---
Commenting out these two lines in pixelSnapBackgroundImageGeometryForPainting() makes the bug go away:

tileSize = LayoutSize(snapRectToDevicePixels(LayoutRect(destinationRect.location(), tileSize), scaleFactor).size());
phase = LayoutSize(snapRectToDevicePixels(LayoutRect(destinationRect.location(), phase), scaleFactor).size());

but I don't know if that's a safe change.

Assigning to Alan.
