I could not open this image, but as far as I know, you have a problem with the landscape material. There are several ways to solve this problem.
1-) Be sure to click the "Static" window in the inspector window.
2-) Increase the "Number of Pixel Pixels" in the menu "Edit"> "Project Settings"> "Quality" at the usual time when the variable is set to 4, but I prefer that 8 or 10 check it.
3-) Do not forget about the lights. See their real-time lighting mode, mixed and baked. They should be the same for great scenes.
After this, if your scene is still broken, remove the terrain material and create a new terrain material. Good luck.
