Macbook Pro 2017 15" Display repeating itself multiple times

[Dad-Zilla]

I have a MacBook Pro 2017, 15 inch display. I have been experiencing an ongoing problem (one of several) that causes the display to repeat what it is displaying 2-3 times down the screen. For example if the top of the screen has my web browser open (or any other application) then the image is overlapped again about 1/3rd of the way down the screen with about 50% transparency and then again about another 1/3rd of the way down with say 25% transparency and again at the bottom of the screen. The repeated images tend to have missing lines and tend to bounce up and down slightly making it almost impossible to read the screen. This can only be fixed by closing the lap-top, leaving it for 15 mins or so and then continuing. If I do a screen-shot the resulting image appears fine, with no problem so it is not the content of the image being displayed. I wonder if anyone has some advice on what this problem might be. A short video of the problem is attached.
