[Bug]: Transparent background on openbox, black on xfce

What happened?

Almost 2 months ago, I made a fresh debian unstable installation on a laptop. I installed all my apps there, including conky, and I transfered my .conkyrc (the one I use for more than a decade now) to it. After that, I edited the conky.text part to correct stuff that is related to the hardware changes from the one system to the other (the sensors basically),

When conky runs on xfce though, its background is completely black. For that reason, I also installed openbox there (the wm i use on my main pc since 2009 when xfce was light years behind gnome and kde) and conky is transparent there. As suggested by other online users online with similar issues, also tried setting own_window_argb_visual to true, but nothing changed. As a sideeffect, this variable made conky have a black background on openboox too. Setting own_window_type to normal did not change anything too.

Compositing on xfce is and will remain disabled, I can post a screenshot of the whole desktop if needed, and I have omitted the conky.text part of my config because it is irrelevant with the issue.
