I would like to be able to use Docky or Plank in Manjaro Fluxbox, but they do not work well.A large band of shadow appears close to the dock. This shadow is there even when the dock is hidden.This area cannot be clicked through and any window under it, just like a whole part of the desktop, is thus unaccessible.I have tested mostly Plank but similar problems albeit some different are present with the others.(Wbar works fine, but it has a different logic I suppose.)
Plank dock problem in Manjaro Fluxbox 15.09

The phenomenon, which you described as a large band of shadow, is likely because the window manager Fluxbox is not using any compositing manager.Modern docks such as docky and plank relies on a compositing manager for its appearance rendering and animation effects. This is a default, therefore compositing is required for these docks and there is no way to skip this requirement (when using earlier releases of plank).Latest solution: Update plankAs release 0.10.1, the dock seems to support both compositing and non-compositing environments properly. I have tested this release on Xfce 4.10 with Xfwm.Solution 1: CompositingYou will need a compositing manager that works with Fluxbox. According to this Wiki, the only option with Fluxbox is compton. Not much details, but someone had managed.Solution 2: Non-compositingUse other dock that works even without compositing, such as avant-window-navigator and cairo-dock. The latter seems to work better with compositing. These docks will have solid background when used in non-compositing mode. No compositing means no transparency.Related experienceI have experienced this phenomenon when I had tested docky and plank during its early development in GNOME 2 and Xfce environments. These X environments had their built-in compositing managers, Metacity and Xfwm, which can be turned on and off easily.This area cannot be clicked through and any window under it, just like a whole part of the desktop, is thus unaccessible.However, I didn't remember the shadow had prevented me from clicking the launchers on the dock (it was some time ago, so I can't recollect my testing experience entirely).Additional notesFluxbox Wiki had this howto that explains how to use compositing with Fluxbox using xcompmgr, which was said to be nothing but eyecandy. Since its development had discontinued, its fork compton took over the role, which notably known for its solution to tear-free experience in Xfce.Dock with compositing and non-compositingTo describe the difference between two solutions above, I have used avant-window-navigator in Xfce environment to demonstrate the effect.In the first screenshot, the information dialog is partially visible under semi-transparent dock background and has drop down shadows around the information dialog itself.In the second screenshot, the information dialog is no longer visible and hidden under the light grey solid background and no more shadows.
