I'm wondering how to reduce/remove the window shadow on OpenSUSE 13.1. It seems to only apply to some windows (Files/Nautilus, Settings...), but it's way too big for my liking, especially since you can't click through it.

I can't find any settings for it in the Tweak Tool and the often suggest CompizConfigSettingsManager doesn't seem to exist on the system or YaST.

Does anyone know a way to reduce the shadows?
