Please, Help me!

Hello! "End Screen" YouTube (new feature) work wrong. I can not move the video on the screen, there should be a visible grid, and for example, an icon video or a subscription button, can move anywhere (on the left in the lower right corner, in the middle, etc.). I checked other browsers, and everything is fine. I wonder it is connected with the Opera browser?

Look, here seen grid and can be moved dynamic element:
