Terrain Problem

I don’t know if it just happen to me and to anyone but how i can fix the graphic terrain problem?
It’s look horrible! i controlled every single part of setting and function on roblox studio for see if maybe is the graphic low but nope nothing.


If someone know what is this, can you tell me how to fix it!

It appears to be a terrain visualization in Studio Settings. I don’t mess with it too often, so I’m unsure of what the exact setting is.
