background mode does not work with polybar pseudo transparency

As the name implies, the pseudo transparency stuff stay still and does not change with background mode.
It works with root mode, btw.

Thanks for reporting,
Background mode is spawning a window with a background typehint that is not fully supported by all window managers. Not sure if I can change that behavior, what window manager/desktop were you running polybar on?

I simply use bspwm. I guess this might be something we need to work with polybar code, for I guess polybar might use the root window to feed its pseudo-transparency(I am not sure for I haven't looked through the code of polybar......).
