Sometime inactive windows not blurred

[Dimentium]

I use AutoRaise app for automatic window activating under pointer (hover cursor). Same functionality has Yabai.

Now I see what sometimes window which lost focus doesn't blure, until I do 'click' on active window. Sometimes it works fine, sometimes doesn't. I don't know why.

Is it possible to detect focus changing without click waiting?
