When I play an MP4 video with Videojs under IE11, when the progressControl is set to true, the browser will be minimized, and the CPU will rise to 30%, causing the IE browser to become unresponsive. If the progressControl is set to false, the CPU usage will be Stay at around 2% and there will be no browser stuck

The progress control is enabled by default and Video.js works fine in IE11Win10. Can you provide a test case of your scenario?

Also, I just tried the following option and didn't see any unexpected spike in CPU:

var player = videojs(vid, {
  progressControl: true
});

You have to minimize the IE window to see what I said. If you keep the window visible, it won't happen. What I said is the problem. If CPU goes up, the IE window will be maximized at this point, and CPU usage will drop to normal.

I can reproduce that, though, when verifying on a page with just Video.js, it doesn't get as high. Also, it drops when the video isn't playing.
There's definitely more performance fixes that we can do though it's weird that this is happening only on IE11

[jinyaqiao1102]

Will this performance problem be solved in the near future?

I've been able to track down the issue an opened #5879 which I believe fixes the problem.
