17.04에서 18.04를 설치하고 (17.10을 잠시 지나서 테스트하지 않고 18.04로 점프했습니다) gnome-shell에서 CPU 사용량이 높으며 사용 가능한 모든 CPU 시간이 거의 걸립니다.

먼저 nvidia 드라이버를 사용한 다음 인텔 그래픽으로 전환했지만 여전히 동일한 동작입니다. Unity 셸로 전환 할 때만 중지되지만 Unity에서 어떤 이유로 든 소리가 없습니다 (!). 나는 여기와 Reddit에 대한 몇 가지 보고서를 보았지만 어떤 일이 일어나고 있는지에 대한 단서조차 해결책을 제공하지 못했습니다. 기본 18.04 설치와 함께 제공되는 것 이외의 다른 gnome-shell 확장자는 없습니다.
