iTunes text artifacting

There’s a small visual hiccup with the latest iTunes (version 5). I don’t know if it’s my use of ClearType for the display, or what, but when I retab into itunes it seems to suffer from the artifacting until a repaint is forced.
These images have been doubled in size from what’s on the screen. The first one has the ghosting/artifacting.


The second doesn’t have the ghosting.



It’s not me, I’m certain I can see the artifacting, I’m almost completely convinced that it’s cleartype, as I had a similar problem with gvim and, of all things Delphi when I used TrueType and OpenType fonts. The fix for that software was to use a fixed-face font.
Ok, that’s definite then. I installed the Microsoft ClearType tuning wizard, and poked the configuration until I was happy with it and I can’t see the artifacting any more. What I’d like to know is why Microsoft don’t ship this in the control panel, because damn, but it makes me much happier with cleartype.
