Hey Mattches,
Thanks for taking a look over this extremely frustrating issue.
On my Mac I can’t reproduce this issue either, only on my Windows11.
The scrolling seems to be part of the issue and best I could describe it right now is that when a page is loading while scrolling with Mouse3, the second video stops.
As of testing right now (with a fresh PC boot) the video infinite buffering seems to be somehow a combination between some graphical load and internet load.
For example, if I have 2 videos, both being visible in the front view of any of my desktops, they will stop loading all together.
The same happens when I scroll down any text that has not yet been loaded in the browser, the video becomes unresponsive.
The weirdest part about it as I said. I cannot reproduce it in chrome/firefox, but I can reproduce it in brave using : incognito, new profile or guest profile.
Here is the console log from one of the tabs:

The moment I hit pause I get the above error (blocked by client) when I unpause one of the videos, the other magically starts working.
