It's a bug in the font that appears when the bytecode interpreter is
turned on. It doesn't appear with auto-hinting, by the way on my tests.

There is nothing we can do if you turn the bytecode interpreter on.
Times New Roman Italic is simply not suited for anti-aliasing at small
pixel sizes with native TrueType hinting..
