Squared border on 5.x looks bad

Just look at the corners, can we restore previous behavior?

[koekeishiya]

No, it is not possible to restore the previous behaviour. See the issues linked to #1430 for history. This is one of these cases where no matter what I do, some people are not satisfied.

It would be possible to make it look a bit better by drawing the border at double width and draw one border width outside of the frame and one border width inside of the frame. This also looks better for rounded borders, since you can then set the border radius to 9, which exactly matches the systems border curvature: https://github.com/FelixKratz/yabai/commit/4a9b6ca5367b5068b55c64e01dc70e7fe36c3f6a

That doesn't look particularly good when combined with window opacity, in my opinion.

[FelixKratz]

Another approach would be to just fill in the characteristic system border radius up to the supplied border radius with a mask. This would fill out only the edges of the border.

[koekeishiya]

Well, that ties in to my previous caveat with the new border system in general (mentioned in several of the linked issues); there is no way to accurately determine the corner radius/mask of a window. Sure, most windows use the same, but from my experience it varies between applications, so there is always going to be something that looks "off".
This is exactly why until now I have opted for the square-borders approach.

It really is a pick-your-poison situation imo.

[koekeishiya]

So it might be possible to detect the corner radius by taking a screen capture of the window upon border creation and simply iterate through the pixels and check which pixels are basically fully transparent, and adjust the corner radius automatically based on this.

[diocletiann]

Can you force windows to render in legacy fullscreen mode? It would automatically give you square corners, and in many cases auto hide the title bar. Apps that allow this natively look great!

I would like this to roll back to the old look too :)

I would love to have the option of "inside" borders but for a different reason; I want to know which window is selected but I don't like having gaps between windows. Therefore I'd like to be able to configure a 1px "inside" red border and 0 window gaps.

This might be an unpopular opinion but it seems like more people are using the borders than there are people using transparency.

[24unix]

Transparency ist the main reason for me to use yabai.

[brorbw]

@24unix so you don't use borders or any of the other features of yabai?

[24unix]

@brorbw No borders. Three displays. The middle with bsp, the external with float. But without transparency I wouldn't use yabai, bsp is not so important to me.

[brorbw]

Fair enough - I didn't expect anyone to use a tiling window manager and then only use it for transparency. Guess my ignorance got the better of me. That being said. Personally I don't like the rounded corners and I would like it to go back to the way it was before. I don't care about the transparency nor the animations.

[koekeishiya]

#984 #715 #801 there is a wide range of opinions regarding this topic; as I said before this is a pick-your-poison situation. For now, make a fork and adjust the border to your liking.

[brorbw]

The ability to pick inside or outside borders. Maybe even automatic if border_radiusis 0 🤷🏻

[brorbw]

May I add that the round borders don't look particularly good on square windows

What OS version are you using? I read that Apple has added round corner and there is not a simple way to change it to squared corner. Is it right?
