no roundness :(

I built and installed your fork, I added border_radius 16 to my config and it seems like it accepts it as I don't get any warning or errors, however, my window borders remain square

This is my i3 config, I believe the only relevant part is the border_radius 24 line, but I might be missing something.
Since i3 accepts this config I assume that I loaded the correct binary and built from the correct source.
I'm using picom if that matters

I noticed that if I stack windows they become rounded, but even weirder, after unstacking them they remain rounded but their size gets messed up, the height of the windows get increasingly longer
