How to disable automatic sharpen preview

[Antonio Angelo]

Hi all!

My environment is:
DigiKam 4.12.0
OS: Ubuntu 16.04

When I edit my photos with Enhance>Sharpen>Refocus, I want to disable from
automatic start of sharpen preview each time I attempt to zoom the photo.
This is quite annoying and makes difficult to move and zoom the photo
itself and for this reason I prefer manually Try each time, using Preview
on mouse-over.

Is it possible? How to proceed?

Thank you for your attention.
