How can I keep the popup windows relative with parent when parent move

I has a video application.In the parent windows,i create a popup windows to show video. I put this window xid to the third lib to draw. when I call gtk_window_begin_move_drag to move parent,the popup windows keep in the old pos.

so I connect configure-event,and set the popup windows position in same time,But the movement effect is very poor.when move faster,the popup windows move delay,can not move synchronization

I use gtk+3

anyone can answer me?

anyone can give me help?
