Wrong positioning on multimonitor
If you have a window on the left monitor focused and then move the mouse through a bar to the right monitor and then call e.g yad --calendar --mouse yad gets the mouse position right but not the monitor.

I tested it with polybar and lemonbar and happens on both. I'm using bspwm but this happened on i3wm too.
On the other hand jgmenu behaves properly.
I'm gonna take a look at this myself but it's my first time with C so I don't think I will be able to fix it.
Is this issue still actual?
Im not using bspwm anymore but it was still happening about a month ago. I just tried on awesomewm + the awesome panel and if the mouse is over the bar yad spawns in the correct monitor but at the top left corner (the bar is at the bottom). Same thing happens with awesomewm + polybar
I can confirm this issue still exists on i3wm with yad 4.1.
