swaybg and wbg are starting a new instance each time wallpaper-set is
called. That means that if wallpaper-set is used more than once in an emacs 
session, multiple
wallpapers set.
In case of wallpaper applications that work like that, running instances
of wbg/swaybg should be terminated before loading new once.

with those "stand-alone" wallpaper applications, the wallpaper process
is attached to emacs if wallpaper-set is used.
With that the wallpaper only stays as long as emacs is running.
I think the process should be detached from emacs.

I'm not shure if that information is useful,
please let me know if it is, or if there is something i should test next.
