Hi, I just migrated from Gnome to KDE (a fresh Kubuntu install) and I have this ugly fonts all over my workspace. I Googled for a while and tried some workarounds but non of then worked. I also tried to enable Anti-Aliasing on System configurations with no success. Thanks.

You may have a corrupt font cache. Try removing ~/.fontconfig then logging out and back in again.

Thanks for the reply. I upgraded to KDE 4.3.4 and now the fonts are just fine. Thank you for the support.
