Pretty noobish of me 
But for some reason i can’t figure out how to turn off shadows in GTK programs on KDE, Window decorations in settings seems to affect only qt, i remember it wasn’t the case some time ago 
Any ideas?
Are you using gtk3 or gtk3-classic?
gtk3-classic removes a lot of the gtk client side decorations.
gtk3
Thx!
Well, preferably i’d still like to just have a control over usual gtk3 though…
Feels like kwin's job
Are the shadows being applied as an effect in kwin or are they part of the CSD?

First of all: this is a big misunderstanding. KWin does not have any shadows. KWin does not add shadows to any windows at all. There is no such thing as a generic shadow which KWin would add. Due to that of course KWin cannot add shadows to client side decorated windows.
Instead KWin provides a shadow rendering service
