Debian 8.5와 gnome 데스크탑이 있습니다. CPU 사용량이 70%를 초과하는 경우가 많습니다 gnome-shell(100%를 초과하는 경우도 있음). 왜 이런 일이 발생합니까? 지금까지 프로젝트를 실행하면 python-pygamegnome-shell의 CPU 사용량이 100%가 넘고 게임이 매우 느리게 실행됩니다.
편집하다
이 CPU 사용량은 실제로 창을 잡고 움직여도 발생합니다! 심지어 이로 인해 gnome-shell의 CPU 사용량이 100%를 초과할 수도 있습니다. 누구든지 도와줄 수 있나요?
다음은 일부 터미널 출력입니다.
