YouTube videos need a refresh to load correctly playback error

[lemonadetime]

On Windows 10, Edge.
When enhanced-h264ify extension is enabledd, new video page shows like this:

It takes a page refresh to play normally:

if I untick the block options and click open new videos in the same tab, still the same situation:

Then I refresh it, things go back to normal, but of course that way the extension is totally not showing its capabilities:

This happened to https://github.com/erkserkserks/h264ify too. In fact I just installed h264ify today and it caused exactly the same problem.

I have disabled h264ify and made sure YouTube videos can play normally again before I enable enhanced-h264ify to do the tests.

I just found it can work fine if I open a video on a new tab. Seems like it has to be a fresh page for the extension to work.
