I was working on a scene, in EEVEE, the shadows looked great, and after working on the geometry for a while, I noticed the shadows look jagged and really low-res. Here's the comparison between an older version that looked fine and the current jagged version :
I still have the same Render settings with the Cube size and Cascade size set at 4096px.
When I copy all my new models in the old file, the shadows look fine, so it has to be a setting on my new file that broke the shadows. Is there another setting I might have missed and changed by accident that changes the quality of the shadows?
I figured out it was a problem with my camera because if I import the old camera into the new file, the shadows look fine. I'd still like to know what causes it because AFAIK every setting between the two cameras are similar.
I added a minimal file that shows the problem, you can switch between the two cameras in the Scene tab, and you'll see the issue :
