Five full-screen buttons in embedded Youtube videos

I am using Android Chrome. Why I am seeing four additional full-screen buttons in the embedded Youtube players as shown below, instead of the play and other buttons. The issue reproduces on various websites. The problem reproduces even if I check the "show in desktop mode". The videos start to play when I click the left-most button where the play button should be. Sometimes the four gear icons start to flicker replacing the full-screen buttons. These issues appeared recently, maybe a couple of weeks ago. I use Chrome version 113.0.5672.77; the Android is the latest native 12. The phone is CAT S42.
