Only in Firefox 4, you can see that the "% Risiko" indicators are cropped by the underlying box. 

Compare the following screenshots:

Do you get the 3.6 behavior if you disable direct2d in preferences?

Once I set gfx.direct2d.disabled;true there doesn't seem to be any cropping.
So, Direct2D seems to be the cause.

Probably invalid, then.  Direct2D being enabled means DirectWrite is used, and that uses slightly different font metrics than GDI does.  And this site makes bogus assumptions about the font metrics that will be used (e.g. on Mac it's cut off for me even in 3.6).

There's no % Risiko label anymore. Let's mark it WORKSFORME.
