Differences in font configuration between Gnome and KDE

[Sandro Mani]

Hi,

I'd like to build Qt-Creator against Qt5 for F21+, however I dislike the 
way Qt5 apps render fonts under KDE and am therefore hesitant to push 
the update, see [1] for a screenshot comparing the font rendering Qt4 
(left) vs Qt5 (right) on KDE.

Not the actual question: I've tested the same Qt5 build on Gnome, and 
oddly enough, there fonts look okay! So I was wondering, is there any 
tool which dumps the active font configuration (I guess that would be 
the Xft parameters?), so that I can find out what is causing the "bad" 
rendering on KDE?

There's also a bug report on the issue, see [2].

Thanks,
Sandro
