kxftconfig.cpp in kdebase4-workspace 4.11.2 in 13.1 is the same with the one in kdebase4-workspace 4.11.12 in 13.2. I am starting to think the reporter triggered a false alarm, or it's not antialias related at all. I will try on my 13.2 virtualbox tomorrow to see how I can change the broken rendering good again. That may help. Marguerite
