Is there some other alternative to implement that effect on my system, because even GNOME has a direct solution for this effect, why is it so hard to implement in KDE?
You should then have the option available in your System Settings:
I can’t guarantee that it will work properly (for example, I noticed that my autohide panel stopped hiding itself when the effect was active). So, you might want to keep an eye on the original & fork just in case further changes are made.
