MacBook Pro 2018 video screen error?

So I have the same problem from the beginning.

When I watch videos on YouTube and then switch to Netflix, I often have a strange mistake. (difficult to describe)

Let's take a look at Youtube and watch the show with the mouse.

20 minutes later I watch Netflix and get short on-screen moments from the mouse. Like a still from Youtube. Although I closed Youtube.

It kind of flickers in and then it's gone again. The thing is it is now so far that the statue remains until I click.

Currently I watch videos about safari.

Try it with another browser, for example Opera.
