Question Blurry areas in terrain when using orthographic camera

I have created a terrain with pretty much standard settings. When using orthographic camera I have blurry rectangular areas both in scene view and in game view. When using a perspective camera I don't have this problem. I am using Unity 2021.2.0b16 with Terrain tools 4.0.3.

Here is a screen shot when using orthographic camera:


It looks like this is somehow related to Mipmaps:


Any ideas what is causing this? Is this a bug or is terrain not intended to be used with orthographic cameras? I did not have this problem with earlier versions of Unity (earlier versions of 2021.1), but I would have to research to find out when it got introduced (I had ignored this problem for a while) and I might even be wrong with this statement.

Thanks for any help.

Best,

This problem is tracked as regression bug and it got introduced in 2021.2.

One year later... still an issue in 2022.2.1f1...

 

I wasted so much of my time. I wish I knew orthographic cameras were not friendly with Terrains. Frustrating!

 

I've fixed it bu upgrading to 2021.3.24f1.
