I am doing a course on Pygame where I have to write code for a game. But the code is not displaying the full background. I have attached three images: how the code is; what the pygame window is displaying for me ; and how it should look like according to my course. I have tried checking my code, getting help from elsewhere. Also, I have tried it on two laptops, one has Windows 10 and the other has Windows 11. Windows 11 doesn't display any part of the down arrow. But, Windows 10 displays some of the down arrow (as you will be able to see in the attached image). I will be very grateful if you could get back to me with a solution to this problem.
