For example the fonts in Firefox are poorly defined and the Minecraft game presented strange pixelation.
Other than that, desktop fonts and icons are correct.
Yesterday, in Mageia 2, all worked OK.
Additional Info:
OS: Mageia 3 (official)
Desktop: KDE
Graphic Card: nVidia 7950GT (proprietary driver 304.84, tested both from the repos and from the official site)
If more info is needed, let me know.
