Picture in picture mode lacking

New M4 Pro Macbook Pro. Picture in picture mode in Safari freezes every 23 sec, for like 2 sec and then it continue for another 23 sec, freezes for 2 sec etc etc.

It's done that since I got the Macbook. My old Intel Macbook didn't have this for me, huge problem.

Chrome doesn't have this problem, only Safari.

Lates OS (15.3.2) no Safari extensions.
