Thank you for forwarding the e-mail.

I try to get the desktop size from _NET_WORKAREA and _NET_CURRENT_DESKTOP.

After KDE panel runs, the height of root window != the height of _NET_WORKAREA \
because KDE5 panel is allocated. I wish to move my panel to (the width of root \
window, the height of _NET_WORKAREA) But When I try to get the the height of \
_NET_WORKAREA during the login, the height of root window == the height of \
_NET_WORKAREA because KDE5 panel is  not allocated yet. So the position of my panel \
and one of the KDE panel is duplicated.

This is the expected result.

But actual result at login time is duplicated because KDE5 panel is not allocated:

After KDE5 panel runs, my panel gets the right position because the height of \
_NET_WORKAREA returns the right value.

I'm finding how to listen the changes in the property.
But I don't have to listen the change in GNOME and XFCE. I can get the right value of \
_NET_WORKAREA at login. I guess KDE5 panel might be slow to be launched.

Probably I can use "notify::size" signal for GtkStatusIcon to listen the panel size.
But I don't know how to get the change of the panel size in KNotifications.
I migrated GtkStatusIcon to KNotifications recently since KDE5 does not enable \
notification area by default. I use both the custom panel and panel icon of \
KNotifications now.
