在我的 Ubuntu 16.10 上，Chrome 的最新两个版本在外接显示器上播放视频时会比较慢，只有当该 chrome 窗口/选项卡未获得焦点时才会出现这种情况（即，如果我单击笔记本电脑显示器上的另一个窗口，视频才能在外接显示器上全屏播放）。
当视频出现抖动时，我注意到 Xorg 进程占用了 100% 的 CPU。当我单击另一台显示器上的另一个窗口时，视频播放正常，XOrg CPU 占用率立即下降。
这不是世界末日，但在尝试观看电影时总是必须将鼠标移出屏幕并单击笔记本电脑显示器上的随机窗口，这很烦人！

关于 Ubuntu 报告Intel® Ivybridge Mobile
我运行了英特尔图形工具更新，并确保我运行的是最新的 Chrome v60.0.3112.90（官方版本）（64 位）
我已在这里尝试过答案：Chrome 在全屏模式下运行缓慢（与 Flash 无关）无济于事。

答案1
这是因为 Chrome v59+ 从 Chrome 中删除了 Flash。
经过多次反复尝试，我发现最简单的方法是安装 Google Chrome Beta 来使用 Flash，而使用 Chrome 稳定版来处理其他所有事情。
我下载并安装了这个.deb 文件：http://sagasl.uccuyosl.edu.ar/mirror/dl.google.com/linux/chrome/deb/pool/main/g/google-chrome-beta/google-chrome-beta_58.0.3029.81-1_amd64.deb
然后通过启动
google-chrome-beta
然后转到chrome://flags/
并禁用
Prefer HTML over Flash Mac, Windows, Linux, Chrome OS
Prefer HTML content by hiding Flash from the list of plug-ins.
# prefer-html-over-flash
然后重新启动。
现在，视频应该可以全速全屏播放，不会因使用优质（！）旧闪存而出现抖动。
