I understand the concept of open source to a certain extend.
I have a distribution with a first time configuration for KDE, where I can disable some screen effects.
Happily there is not a very long list of screen effects and I do not have to spend 10 minutes to configure. I am not lazy, I am 'efficient'.
The screen effects of KDE do not give a busy look yet.
Soberness and selection can be nice. Sometimes less is more.
