Solved: Terrain textures blurry in 2018.3

Hello,
I just made a small test with a simple scene originally made in unity 5.4, ported to unity 2018.3.
Check the 2 attached images. All the quality settings of the project are the same, the terrain in both cases use the standard terrain shader and all the textures use the same settings (mipmaps and compression). The textures on terrain in 2018.3 clearly look blurry. Any ideas on what is going on ?

 

To anyone who may be struggling with such an issue. The problem is the conversion of the project from an older Unity version to a newer one. Deleting everything except the Assets folder in the project directory and reopening the project in the newer Unity fixed the problem.
