在某些时候（我不记得它是什么时候开始的），出现了某种幽灵窗口，它只有一个边框（显示为圆形，但表现为矩形），阻止鼠标点击，并且当我最小化所有窗口时不会消失。
这可能是什么，可能是什么导致了这种情况，最重要的是，我怎样才能摆脱这种情况？
以下是一些可能有助于诊断问题的附加信息：
- 这似乎不影响锁屏。
- 当我单击窗口时，Alt-Tab 窗口切换器的行为非常奇怪：
- 如果我在幽灵窗口之外单击，它会立即切换到我单击的窗口。
- 如果我在幻影窗口内单击，它会立即关闭窗口切换器，但直到我将鼠标移到幻影窗口之外才会打开新窗口。我的鼠标的最终位置似乎并不重要。
- 我使用 Xfce 版本 4.18 和 GTK 版本 3.24.37，作为 Debian GNU/Linux 12 (bookworm) 的一部分。
- 我有 xserver-xorg 版本 1:7.7+23 和 xserver-xorg-core 版本 2:21.1.7-3。
- 屏幕顶部的面板不会响应鼠标点击，但它显示的数据会更新，并且当我使用键盘快捷键激活应用程序菜单时，它会起作用。

以下是一些屏幕截图，用于说明当我更改显示设置时它的行为方式。它在缩略图中并不明显；单击它们即可查看完整尺寸的版本。
答案1
更简单的解决方案：（先xkill -frame尝试xkill？）
- 运行
xwininfo -d :0 -all（谢谢@xhienne！）并点击幽灵窗口。将字符串记录在引号中Window id:，并在后面记录数字Process id:。 - 运行
kill后跟上数字Process id:。 - 如果不需要的内容消失，请通过运行由引号中的字符串和后跟 组成的命令来恢复
Window id:它&。
