几天后，undo通过Ctrl+进行的操作z不再有效。
我的系统是Kubuntu 23.10 x86_64DEPlasma 5.27.8的。
该问题仅出现在 X11 上，而不会出现在 Wayland 上。
此时，我已经没有想法了，非常感谢任何帮助。
到目前为止我尝试过的：
- 在 NVidia 驱动程序 (535) 和 nouveau 之间切换 - 没有区别。
- 在其他键盘布局和语言之间切换 - 没有区别。
- 杀死 X 客户发现
xlsclients -la- 没有区别。
以下是我收集的一些输出：

/home/kwe/.vscode/extensions/ms-python.python-2023.22.1/CHANGELOG.md:1. CTRL+Z is deleting cells. It should only undo changes inside of the code for a cell. 'Z' and 'SHIFT+Z' are for undoing/redoing cell adds/moves.
