请问HN：Netflix怎么会出现这样的bug？
Netflix在我的设备上出现了一种状态，在每个浏览器中，音频正常播放，而画面却冻结或变黑。我尝试了Firefox、Chrome和Safari。<p>重启我的Macbook Pro可以解决这个问题，但更换浏览器或清除所有缓存和Cookie并不能解决。<p>这怎么可能呢？难道这不意味着浏览器作为沙盒的整个概念被破坏了吗？我猜这可能是Netflix在管理我观看设备数量时引发的某种错误。<p>这个错误真让人困惑。这里有没有人知道我还能重置或清除什么（不重启电脑）来解决这个问题？<p>这个问题几乎每天都会发生，频繁重启实在让人很烦恼。

Netflix gets into a state for me where, in every browser on my device, the audio plays, while the picture freezes or goes black. I've tried Firefox, Chrome and Safari.<p>It is fixed on restarting my Macbook Pro, but changing browsers or clearing all cache and cookies does not fix it.<p>How is this possible? Doesn't it mean that the whole concept of the browser as a sandbox broken? I assume it is somehow a bug caused by Netflix attempts to manage the number of devices I am watching on.<p>It's such a baffling bug. Does anyone here have any idea of what else I can reset or clear (without restarting the computer) that might fix it?<p>It happens pretty much every day, and it's quite annoying to have to restart that often.
