去年我使用 ubuntu 上的 OBS 录制了 100 多个教育视频，所以我大致知道如何使用该程序。由于已经有一段时间没用过它了，我决定运行它来设置我正在开发的新项目。当我这样做时，底部的每个面板都翻了一番。不仅仅是控件，还有音频、源、场景转换等，它们以一种相当有故障的方式相互重叠。这使得该程序对我来说毫无用处。
所以我认为可能是不同版本的配置文件不匹配。我决定删除配置，然后 $rm -rf .config/obs-studio 并重新启动。结果相同。这是 ppa 版本。所以我 apt 清除了它，再次清除了用户配置，删除了 ppa 并安装了 debian 软件包版本。
结果相同！因此我再次清除了配置并尝试了 snap 版本。结果仍然相同。
我从终端运行它，看看是否有任何明显的错误。无法加载模块“decklink-ouput-ui.so”的“en-US”文本的警告很突出，但显然对大多数人来说这不是问题。我只在 debian repo 版本中这样做

我能想到的唯一重大变化是我为我的 AMD Radeon Pro W5500 切换为使用 AMD 驱动程序。如果我找不到其他办法，我接下来会尝试这样做。我希望您理解，切换图形子系统不是我轻率做的事。所以我希望有人能想到其他可能的原因，或者确认没有愚蠢的图形驱动程序的其他人也遇到了类似的问题。
干杯
编辑： 我忘了说了。如果你从底部取消停靠设置面板，则只有一个面板，并且重复项会消失。
更新：
- 今天早上卸载了 amdgpu-pro 驱动程序，但问题仍然存在。
