答案1
您可能遇到不止一个问题。
gnome 外壳
我们将从 gnome-shell 扩展开始。你有太多扩展，其中一些是崩溃gnome-shell，其中一些导致 gnome-shell 的 CPU 使用率过高，其中一个可能导致屏幕伪影，其中一些安装了两次，还有一些安装在了不适当的位置。
首先https://extensions.gnome.org/local/和禁用所有扩展.然后使用以下命令重新启动 gnome-shell：
ALT+ F2，在框中输入r，然后ENTER
我怀疑屏幕伪影已经消失，运行速度应该会更快。如果真是这样，我们将进行下一步。
删除这些扩展...
sudo rm -r /usr/share/gnome-shell/extensions/*gcampax.github.com
重新安装这些缺失的扩展...
sudo apt-get update
sudo apt-get install gnome-shell-extension-appindicator
sudo apt-get install gnome-shell-extension-desktop-icons
使用以下命令重新启动 gnome-shell：
ALT+ F2，在框中输入r，然后ENTER
系统稳定后，重新启用一次一个扩展，同时留意屏幕伪影、“堆栈跟踪”错误/var/log/syslog*，或在top命令中看到的高 gnome-shell 使用率。gnome-shell CPU% 使用率应低于 3%。
请勿从 gcampax.github.com 重新安装扩展“包”。
不和谐
Discord 存在一些安全和隐私问题。请参阅我接受的答案20.04 版中磁盘空间突然无缘无故用完了解详情。
我最担心的是它会“监视”你与 Discord 一起运行的其他应用程序。这不关“他们”的事。
更新＃1：
删除 Ubuntu 并迁移到 arch（Manjaro）。
