Usando o Audacity no Debian Jessie, abri um mp3 de álbum completo (cerca de 41,6 MB, 43 minutos) e quero dividi-lo em mp3 menores usando rótulos. O problema é que, às vezes, quando começo a editar um rótulo, ele quase congela (leva vários segundos para digitar cada caractere). Se eu pressionar Alt+Tab para alternar entre outro programa, o caractere digitado será exibido imediatamente. Estou usando muito Alt+Tab para digitar mais rápido! Posso ver que ele está usando pelo menos 80% da CPU, até 96%, mesmo quando ocioso e sem jogar. (As teclas de seta não requerem Alt+Tab, apenas as teclas de entrada.)
Abri um mp3 menor (cerca de 6,6 MB, menos de 3 minutos) e o uso da CPU foi de cerca de 10%. Depois de adicionar alguns rótulos, primeiro tive um flash branco em toda a tela (depois de adicionar/editar apenas o primeiro rótulo!), depois alguns caracteres com diacríticos (como ó, á, ê) não funcionaram (no segundo rótulo; eles estavam apenas trabalhando no arquivo maior) e a CPU voltou para 92-96%. Também posso ver o atraso começando durante a digitação (mas menos segundos entre cada letra).
Além disso, se eu digitar duas ou três letras entre cada Alt+Tab, elas provavelmente aparecerão na ordem invertida.
Eu conseguia digitar rótulos sem problemas antes, isso começou a acontecer há pouco tempo (algumas semanas ou meses?).
Estou usando o Audacity 2.0.6 (diz que é a versão mais recente disponível para Debian) e tenho 8 MB de RAM, então acho que a memória não é um problema.
O Audacity costumava ser um ótimo programa. O que possivelmente está acontecendo? Será este possivelmente um daqueles vírus que só servem para abrandar as nossas tarefas?
Se eu executar o Audacity a partir do terminal, é isso que vejo.
