复制或粘贴时系统冻结

Question

我正在使用 LibreOffice

\n\n

版本：6.0.7.3\n构建 ID：1:6.0.7-0ubuntu0.18.04.10\nCPU 线程：12；BS：Linux 4.15；UI渲染：标准；VCL：gtk3；

\n\n

在 Ubuntu 18.04 LTS 上。复制某些内容时，系统会冻结几分钟。\n复制之前在控制台中运行 top 时，我可以看到进程 gjs 占用 100% cpu 并使用所有 RAM 和交换空间。系统需要几分钟才能再次顺利运行。kern.log 显示了这一点：

在 Writer 中，这种情况大约每 10 次发生一次，但在 Calc 中，每个复制操作都会触发此情况。Nautilus 在粘贴文件时也经常触发此错误，并出现相同的症状。

我不知道如何从这里继续。有什么建议么？提前致谢！
