Chromium загружается слишком долго! (1+ минута)

Начиная с Lubunu 19.10, хром, установленный через Snap, загружается более 1 минуты! 19.04 загрузился быстро. На 19.10 активность ЦП и диска пассивна. Поскольку Lubuntu не основан на gnome, является ли связка ключей gnome причиной этой проблемы? Начиная с командного терминала, я получаю следующее сообщение:

Закрытие браузера дает мне следующее:
