Patches of Terrain lose detail when zoomed in with Orthographic Camera



Reproduction steps:
1. Open the user's attached project
2. Open "Assets/OrthographicBaseTerrainBug"
3. Enter Play Mode
4. Change the "Size" parameter to a smaller value on the "Main Camera" in the Inspector

Expected result: The Terrain texture is fully rendered when "Main Camera" has zoomed in
Actual result: Patches of the Terrain lose detail when "Main Camera" has zoomed in

Reproducible with: 2021.2.0a1, 2021.2.2f1, 2022.1.0a15
Not reproducible with: 2019.4.32f1, 2020.3.22f1, 2021.1.28f1

- Terrain texture is rendered correctly when using "Perspective" Projection
- Same behaviour can be observed in Scene View when having Orientation set to "Iso"

    I have the same problem in 2021.3.16. I'm using Ortographic Camera. Has anyone been able to check if it was actually resolved?

    I have this bug with 2021.3.16, and disable terrain texture mipmap doesn't help

    Our team was excited about the new 2021. But terrain with an orthographic camera...
    In the LTS version, not in beta, btw.
    Please, fix!

    In effect this bug means that terrain cannot be used in combination with an orthographic camera, because the blurry patches cannot be avoided. I hope this will get fixed. Otherwise it probably should be documented that this combination is not supported.
