Screen tearing / vertical sync issues when playing videos

Hi, 

We are experiencing vertical screen tearing issues when playing videos on Presentation mode.

The problem is the same on desktop and web, with small changes : 

• desktop : always append, videos fullscreen or not, autoplay or not. Deactivating the material acceleration causes the presentation to crash/not open. 
• website : append after the ~3rd video played. Refreshing the page helps, but the problem is just pushed to the next ~3rd video played. We have optimized videos, but it does not help. 

We are on MacOS – Intel and M1 CPU – Chrome and Brave browsers.
