I meanwhile can reproduce it here (with my first optimzed Lucid build).
So far no luck in fixing this.

couldn't find out how.)

Use

(setq default-frame-alist
      '((minibuffer . nil) (undecorated . t) (drag-with-mode-line . t)
        (border-width . 0) (internal-border-width . 8) (drag-internal-border . 
t)
        (menu-bar-lines . 0) (tool-bar-lines . 0)))

because the frame to drag must not have a minibuffer window.  And please
try with gtk and lucid.

Here I can move a top-level Lucid frame and drag its left and top
borders without any problems which seems to prove that the moving
problem is child frame specific.
