The Expected Behavior

1. The borders be adapted to the window's corners when they are rounded, as round-borders-rule should be able to do in i3-wm

The Current Behavior

2. There is a blank space in the borders, as a cut (Like the borders are part of the window itself, being rounded as part of it, thus getting its corner cut).

You can see it in the right Alacritty window in the screenshot that is in this post. I think the rounded corners effect was adapted from Ibhagwan's fork, and as far as I know, this i3-gaps problem should be solved with the rounded-borders-rule.

I noticed this is a fix already made in ibhagwan's fork, which was recently merged with the mainstream (yshui's). Unfortunately this fork is not forked from the original, but to one that is some versions behind from it, I would really appreciate some work in this issue. This bug is really bothering but borders are necessary for a tiling wm in my opinion

FYI I also have this issue and it would be really satisfying to have it resolved. I have a separate issue with the corner the shadow is directed to having an opaque square border and transparent interior, whether it's related.

Same here...
