我正在尝试在 Ubunt20.04 上使用 Opera snap。它已从 Ubuntu 软件应用程序 (snap-store) 加载
Opera 加载速度非常慢。如果从终端运行 Opera，在漫长的加载过程中会显示以下一系列错误：
$ opera

答案1
不要使用 Snap！
几乎所有 snap 加载时都很慢。我不知道是否有 opera .deb 包，apt-get install opera因为我不使用此浏览器，但我尽量避免使用 snap，你也应该这样做。
答案2
不幸的是，由于 libffmpeg.so 文件存在缺陷，Opera.deb 软件包在播放视频时存在已知问题。Snap 软件包不存在此问题。
答案3
我还发现 opera snap 加载速度非常慢。这个问题是由于 opera snap（2022 年中）造成的。并不是因为它是一个 snap。许多 snap 第一次加载很慢，随后加载速度很快。这在大型应用程序（例如浏览器）中尤其明显。在 opera snap 的情况下，第一次运行时的优化似乎没有发生。我正在为 3 个浏览器使用 snap，只有 opera snap 有这个问题。我喜欢 snap 沙盒的好处——互联网的手非常脏——我希望它戴上橡胶手套来拜访我。对我来说，这个好处让重复的缓慢加载不是什么大问题。我希望 opera 团队能解决这个问题，因为可能需要超过 10 秒才能达到可用状态。我还发现窗口总是以默认大小加载，而不是全屏加载——窗口加载参数不会被保存。加载后，其他东西似乎正常工作。
