Version: (using Devel) Installed from: Compiled sources Compiler: GCC-4.2.3 OS: Linux No matter which setting I use, Anti Aliasing doesn't work.
I made some test and it looks like it's a problem with the "Sans Serif" font. AA works in KDE 3.x with this font, but not in KDE 4. Anyway, it's not really a problem since changing the font resolves the issue.
It is strange that only with one font AA doesn't work. Anyway Next Qt 4.5 should have an improved AA system. I'm closing this.
