How to reproduce:
1. Create and open a new project with “High Definition 3D” template
2. Make sure the Editor is running on DX12 or Vulkan graphics API
3. In the Scene window, change Draw Mode to “Unlit”
4. Add a Terrain to the scene
5. Make sure “Sculpt Mode” is selected in the Terrain Tools overlay
6. Restart the Editor

- Changing to “Lit” Draw Mode and back fixes the issue
- Changing to “Materials Mode”, in Terrain Tools overlay, fixes the issue
- Changing to Game view and back fixes the issue
