Weird shadows in Eevee

Why do i get these weird sharp shadows?
This problem occurred to me a few times now.

This one object has nothing but a subsurf level 3 mod on it. Even without it shadows are bad…

is increasing the cube size in the eevee shadow settings doing anything to help with that? (using soft shadows in the same settings could help as well)

sorry for the terrible screenshot, I’m on VDI here at work, need to use phone to screencap.

What kind of worked for me was turning on Contact Shadows and making adjustments there.
