Just to let everyone know - We've isolated the issues to partly us,
partly Qt (which is why removing our Qt libs did the trick for some).
So we have compiled a more recent set of Qt libraries (from Qt 4.3.5),
which can be available on request from Tech Support

Just after sending the above report I notices that smaller fonts, like
super- or subscripts are sometimes still not rendered correctly. By

but then normal text again becomes cluttered.

Well, I am not an expert, but I think that it is Mathematica problem
mainly because it installs some libraries, but it does not care if they
are already installed in the system, nor if they are at least
compatible. You should be or warned during the install that these
libraries are duplicit and
And concerning Gutsy - probably the Qt libraries in Gutsy are older or
compatible with those in Mathematica, so it is inessential which one are
loaded. The fact that the libraries in Hardy are newer, is not bug in

Thanks Tom! You're a genius. I can confirm that this fixes the font

I found deleting the libQt files in the mathematica distribution and
linking to the libQt files (.so.4) in
Art Yes the replacement solves the printing problem. The linking is
probably equivalent to simple delete, since if Mathematica does not find
the libraries in its folder, then it tries to load libraries provided by
the system.
