Question Strange screen problems

[Seba1412]

Good morning, I'm not sure how to explain the problem, I went to the desktop and found it all black (the app icons are visible) and only after I select an area of the screen with the mouse does it "recolour". I have the same problem with chrome, when I move the mouse over some pages or on the bar above the various windows it makes the one I had before reappear. I attach an example screen https://ibb.co/McxbN7Z. The same problem occurs in some apps like Chrome or Discord, it happens every now and then that when I move the mouse it shows me where I move it an old page or an old image, in any case things that had passed on the screen shortly before... I don't know how to solve it and what could be the problem
