This is a plugin for wayfire that adds window shadows. The code was initially a fork of https://gitlab.com/wayfireplugins/windecor but only a small part of that remains in the code.
By default, the plugin will add fast and nice shadows around windows that use server side decorations. Additionally there is an option to make the focused window glow.
git clone https://github.com/timgott/wayfire-shadows.git
cd wayfire-shadows
git checkout backport0.7 # (if necessary)
meson build --buildtype=release
cd build
# meson configure --prefix=... # if wayfire is not installed in /usr/local
ninja
sudo ninja install
As above, you have to change the branch on wayfire 0.7.
