I was fooling around with the Settings panel and must have done
something I shouldn't, because now the fonts for KDE apps are all
wrong. GTK apps are unaffected. I enclose a small screenshot to
illustrate. Note that the left-hand side looks fine, while the right-
hand side is clearly wrong. The same fuzziness affects the Plasma panel
and the Konsole fonts.
I've no recollection of touching the font configuration, but I guess
anything is possible. How can I restore sanity?
