打开终端输入

deepin-editor ~/.config/kwinrc

更改成最大化不去边框，然后注销一下：

BorderlessMaximizedWindows=false

问题又是石沉大海，不了了之

貌似没标题栏? 之前装过top-panel?

改了BorderlessMaximizedWindows=true，肯定最大化没边框啊

部分没有，应该装过，卸载了

楼上回答了

BorderlessMaximizedWindows=true

估计是top-panel卸载前没有去除勾选最大化隐藏标题栏选项的缘故吧

手动没改过，应该是装的主题美化软件改的。改为false注销了，大部分应用都有了，typora还是没有
