Displacement Problems

[Jadefox]

Hi Guys

Can anybody assist me with this problem
When I apply a displacement map the interactive viewport shows it to be almost incomplete
but when I do an actual render it seems to render just fine
Is this a problem on my side or a Corona issue ?

I am attaching images to show what I mean

Displacement is calculated based on camera field of view. Outside of it, nothing will be calculated. When you move your camera in IR, the displacement is not updated.
If you need to have IR feedback, either restart IR, or switch displacement mode to world size.

also changing value displacement updates IR
