Let's put it this way: not common enough for neither the Qt nor the KWin developers to heed? ;)

Of course. But you wouldn't mind if they actually look better, would you?
(Not that that's usually the case with "vanilla" cross-platform Qt software running on Mac; it tends to look as if designed for the visual and/or motor impaired).

A few more screenshots:

One could probably say that the FT+FC rendering shown in those images is not correct for certain glyphs. It's actually more correct than without the Infinality/Ultimate patches to FontConfig (with stock FC the result has a bit of a crushed, too flat look). The main goal for these patches probably lies more in obtaining a pleasant and highly legible quality rather than the most correct glyph shape.

If you want I can share the fontconfig enabler patches for Mac with you, for experimentation (or even bundling).
