remote-viewer is designed in a way that it creates all the display
widgets at once, so it is not related to enabling the additional
display. Basically there may be a race between the widget creation and
 the emission of the "cursor-set" signal.

1st widget created - no initial cursor
"cursor-set" signal
cursor created only for the 1st widget (other widgets do not exist)
2nd widget created - no initial cursor
