YouTube playback on Safari

When I start playing a YouTube video on safari, it plays for a second or two (but the page isn’t fully loaded). Then the video goes black for two or 3 seconds(with the audio still playing fine). Then the video comes back with a bit of lag and proceeds to carry on like fine and doesn’t happen again for the rest of the video. It happens every time so it isn’t random, and I have no browser extensions being used. I’ve tried on chrome and I have no issues there. I’m on a 2018 MacBook Pro and have fibre optic broadband so there’s no issue with device power or internet speed. Really odd

MacBook Pro 15”, macOS 10.14

Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.
