Is there an option similar to “Monochrome” in gnome (Desktop Properties → Font Preferences → Font Rendering tab has 4 options, one of which is ‘Monochrome’); for the KDE and XFCE Desktop environments ? Tried, (for KDE) but haven’t been able to locate it.
With the ‘Monochrome’ option selected for font rendering, I notice that there is less font ‘bleeding’ (i.e. the fonts are more evenly displayed).
