rounded corners leaving a black background

[dqrk0jeste]

setting a solid background color for window makes it appear beyond the rounded border corners. setting it to any transparent color does not. see pictures below.
it not that big of a problem, as i can set the opacity to 0.999 which makes no difference

Yeah, that happened to me.

Try to add

#waybar {
  background: transparent;
}
