嗨，这很难解释，但我展示了一个视频：
https://drive.google.com/file/d/1RLRNbuIlznPPdu0Z8IkhIWWYUeMWr13M/view?usp=sharing
似乎在我的官方顶部栏后面有某种第二个顶部栏……
编辑 1：抱歉，但视频似乎没有足够的 fps 录制，您无法欣赏闪烁。我会尝试搜索 vokoscreen 或其他任何东西，尝试使用具有更高 fps 或分辨率的视频捕获桌面。它闪烁得非常快，并在 openweather 扩展的温度左侧出现温度，在 livepatch 图标后面也出现了一些东西。我尝试重新启动并从零扩展开始。
一些信息：

我在其他帖子中说过，我已经从 20.04 升级到 22.04.1，我正在自定义和清理，并尝试解决问题。这在 20.04 中没有发生在我的 gnome 顶栏上...在我看来有问题，闪烁非常令人不安....
提前致谢
答案1
我解决了这个问题，因为在 Gnome Tweaks -> 外观 -> 启动应用程序中，我有两个或三个应用程序，我猜是升级导致的。我删除它们，问题就解决了。
我想将它们添加回来并逐一删除，以确切知道哪一个或哪些导致了问题。我附上了一张西班牙语的图片，但很容易理解（你总是有谷歌翻译=
谢谢
