Version: (using KDE 4.2.2) OS: Linux Installed from: Compiled From Sources I turn off sub-pixel rendering in KDE4 fonts settings and restart X server. All KDE4 application now render without sub-pixel rendering. All, except Plasma. Plasma uses sub-pixel rendering regardless (Kickoff, plasmoids, widget/desktop menus). I expect to apply font settings on Plasma too.
