Audacity hängt während der Bearbeitung allgemeiner Labels

Mit Audacity in Debian Jessie habe ich ein komplettes Album-MP3 (ca. 41,6 MB, 43 Minuten) geöffnet und möchte es in kleinere MP3-Dateien mit Labels aufteilen. Das Problem ist manchmal, wenn ich anfange, ein Label zu bearbeiten, friert es fast ein (es dauert einige Sekunden, um jedes Zeichen einzugeben). Wenn ich Alt + Tab drücke, um zu einem anderen Programm zu wechseln, wird das eingegebene Zeichen sofort angezeigt. Ich verwende viel Alt + Tab, um schneller zu tippen! Ich kann sehen, dass es mindestens 80% der CPU verbraucht, bis zu 96%, selbst wenn es nicht läuft und nicht läuft. (Für die Pfeiltasten ist Alt + Tab nicht erforderlich, nur die Eingabetasten.)

Ich öffnete eine kleinere MP3-Datei (ca. 6,6 MB, weniger als 3 Minuten) und die CPU-Auslastung betrug ca. 10%. Nachdem ich ein paar Labels hinzugefügt hatte, bekam ich zunächst einen weißen Blitz auf dem gesamten Bildschirm (nachdem nur das erste Label hinzugefügt / bearbeitet wurde!), Dann funktionierten einige Zeichen mit diakritischen Zeichen (wie ó, á, ê) nicht (im zweiten) Label (sie arbeiteten nur in der größeren Datei), und die CPU stieg wieder auf 92-96%. Ich kann die Verzögerung auch beim Tippen sehen (aber weniger Sekunden zwischen den einzelnen Buchstaben).

Wenn Sie zwei oder drei Buchstaben zwischen den Alt + Tabulatoren eingeben, werden sie höchstwahrscheinlich in umgekehrter Reihenfolge angezeigt.

Ich konnte schon ohne Probleme Etiketten schreiben, dies geschah vor nicht allzu langer Zeit (einige Wochen oder Monate?).

Ich verwende Audacity 2.0.6 (die neueste Version ist für Debian verfügbar), und ich habe 8 MB RAM, daher denke ich, dass Speicher kein Problem ist.

Audacity war früher ein großartiges Programm. Was ist möglicherweise los? Ist dies möglicherweise einer dieser Viren, die nur dazu dienen, unsere Aufgaben zu verlangsamen?

Wenn ich Audacity vom Terminal aus laufe, sehe ich Folgendes.
