Description of the issue: Hardware Accelerated Video Decode causes severe lag when watching multiple video streams at once
How can this issue be reproduced?
- Launch the browser
- Open a YouTube video at 720p in a tab
- Open a Twitch stream at 720 in another tab or window (it helps to view them side by side)
- Wait a few seconds to see both video streams start buffering severely
Expected result: Both video streams should play at the expected resolution without any lag or buffering

Additional Information: Windows Task manager consistently shows a single thread out of my 16 thread CPU pinned at 99% usage while this issue occurs. The core usage is much more spread out when hardware acceleration is disabled, allowing for a smoother streaming experience.
