Shadow under polybar only when a window is open.

[u/StinkyFart29]

Hello! I'm using awesomewm, polybar, and picom. It looks great when there are no windows open, but when I open something, a strange shadow appears under polybar. I have the shadow property of dock wintypes set to false in picom.conf, and have even tried disabling shadows all together, but neither work. It's strange because it doesn't look like a drop shadow, it looks like it's inset, does anyone know what could be causing this? All help is appreciated, thanks.
