Steps to reproduce the problem:
1. Set the display scaling of windows to 350% (tested on 4k monitor),
2. Open the URL
3. Press load and seek to 3:24 and active CC
4. Observe
What is the expected behavior?
The subtitltes shouldn't cover the video
What went wrong?
The subtitles cover the video.
Did this work before? N/A
Is it a problem with Flash or HTML5? HTML5
Does this work in other browsers? Yes

GpuProcessHostUIShim: The GPU process exited normally. Everything is okay.
Scaling to 350% is an exaggeration but the problem is, obviously, more clear with that setting.
The most likely scenario is scaling 250% that windows has as the default on this 4k screen.
Edge & Firefox work as expected it's only Chrome that scales like this.
