I am having a similar issue. When I stream https://youtu.be/OqvD4NC-s9E it freezes and pixelates. This video has problems on two laptops. I doubt that it is a performance issue. But anything is possible. Here is system information. I am not using the graphics from the CPU but a NVIDIA graphics card described below. The video runs fine in the Edge and Chrome browsers.
