I can also verify that the issue stops once I remove my grass details.

It might be a bug related with the Unity GUI panel itself... the Inspector window width... resize the terrain inspector window by dragging the border.

I have the exact same problem in unity 2021.3.14f1 without any extra packages. I have not even clicked on the grass tab yet.

after debuging for a while, I noticed maybe the grass system is causing it
