Camera Settings No Longer Show Live View After Update

Regarding the camera settings menu.
Before the update, the actual in-game environment was visible behind the settings screen, allowing me to clearly see how each adjustment changed the view.
After the update, the environment no longer appears, and the differences caused by any adjustment cannot be seen at all.
This is a total downgrade.
I request that you restore the previous functionality, where all changes to the field of view could be confirmed within the same screen.
I cannot understand why such a basic, essential feature was removed.
