I cannot find the setting to enable drop shadows.
Or is there no setting for that?

System Settings -> Application Style -> Window Decorations and click on the icon settings for the window theme selected (in my case is Breeze). There is a tab named Shadows, you can change some values.

If after all the window shadow isn't showing, maybe you have to (re)enable Compositor, at System Settings -> Hardware -> Display and Monitor -> Compositor. For me, OpenGL 3.1 is working well for the Rendering backend .

    Setting the size to 48px, strength to 60% and color to #272727 seems to give a nice effect. Too bad it's not possible to adjust position, since it's mostly visible only on the lower and right side. – lenooh Jun 21 '16 at 01:16
  • dang that is a lot of work digging just to disable these crazy useless eye candy to free up some compute – thang Aug 14 '19 at 00:06
  • I did this but it is still weak compared to Deepin or eOS – Bhikkhu Subhuti Jan 23 '21 at 06:57
  • Re-enabling compositor was the key here (it usually crashes from time to time ;( – Marcin Orlowski Jun 17 '23 at 11:06
