Hyprland border flickers when closing a window with closeWindowDelay

It seems that when a window is closed and closeWindowDelay is set, the border of the active window in Hyprland flickers for a bit.

You can observe it when clicking away from the quicksettings popup window in your dotfiles. Interestingly, toggling the popup via the systemindicator button on the bar doesn't have this effect.

I first thought that the focus was being stolen by something temporarily. So I tried to listen to the activewindow event from the Hyprland socket, but it looks like that the active window didn't even change during the transition.

It is most probably a Hyprland bug from switching focus from layer to client

Yeah, might be something Hyprland-specific. Another thing I'm noticing is that it depends on your mouse click speed. If you tap really fast, the effect doesn't happen.

I recently tried https://github.com/ErikReider/SwayNotificationCenter and it has a functional click-away behavior that doesn't have this problem. I wonder how they implemented it.
