playback issues on YouTube 5

I keep getting audio out of sync with the video on certain YouTube channels, and some 4K streams stutter or freeze for a few seconds before recovering. It's super annoying when a music video stops to buffer even though my internet is fine. Hoping they fix these playback issues soon.
