Сломанные шрифты на Gentoo

Я использую Gentoo с KDE и infinalityнабором патчей. По большей части интерфейс выглядит просто отлично.

Однако в некоторых приложениях шрифт для латинских символов выглядит ужасно. Это скриншот из Thunderbird электронного письма, которое содержит текст на английском и русском языках. Обратите внимание, как красиво отображаются кириллические символы.

Латинский шрифт выглядит как Courier. Это подтверждается диалогом настроек KDiff:

Моя конфигурация:

Я думаю, что моя проблема связана с Gentoo Blocky Fonts . «Гадкий» шрифт выглядит так же.
