I need to open a window without it being managed by the window manager, while the other windows on my screen continue to be managed by the window manager, how do I do this?

I'm willing to edit the application source code if that's the only way, it's written in python using pyglet.
@DKBose suggestion that I needed to disable "decorations" and not the WM lead me to adding this to my app:
Which solved my problem.
