Audacity зависает при редактировании общих меток

Используя Audacity в Debian Jessie, я открыл полный альбом mp3 (около 41,6 МБ, 43 минуты), и я хочу разделить его на более мелкие mp3 с помощью ярлыков. Проблема в том, что иногда, когда я начинаю редактировать метку, она почти зависает (требуется несколько секунд для ввода каждого символа). Если я нажимаю Alt + Tab, чтобы переключиться в другую программу и из нее, набранный символ отображается немедленно. Я использую много Alt + Tab, чтобы печатать быстрее! Я вижу, что он использует не менее 80% процессорного времени, до 96%, даже когда он простаивает и не играет. (Клавиши со стрелками не требуют Alt + Tab, только клавиши ввода.)

Я открыл меньший mp3 (около 6,6 МБ, менее 3 минут), и загрузка процессора составила около 10%. После того, как я добавил несколько ярлыков, сначала я получил белую вспышку на весь экран (после добавления / редактирования только первого ярлыка!), Затем некоторые символы с диакритическими знаками (например, ó, á, ê) не работали (во втором лейбл, они просто работали в большем файле), и процессор вернулся к 92-96%. Я также вижу начало лага при наборе текста (но меньше секунды между буквами).

Кроме того, если я наберу две или три буквы между каждой клавишей Alt + Tab, они, скорее всего, появятся в обратном порядке.

Я мог печатать этикетки без проблем раньше, это начало происходить не так давно (несколько недель или месяцев?).

Я использую Audacity 2.0.6 (он говорит, что это последняя версия, доступная для Debian), и у меня 8 МБ ОЗУ, поэтому я думаю, что память не проблема.

Audacity раньше был отличной программой. Что возможно происходит? Возможно, это один из тех вирусов, которые служат только для замедления наших задач?

Если я запускаю Audacity из терминала, это то, что я вижу.
