To make the widget get erased when it's deleted, the widget
that manages the background graphics has to be told to redraw
over it. Even though pg might be the parent widget, it might
not be responsible for drawing any graphics into the background
of the removed widget, so telling it to redraw would be ineffective
in that case.
So if pg has a 'no box' or 'border only' box type, it won't
draw over the background, leaving the removed widget behind
on the screen.
Try telling the parent widget responsible for the background
to redraw. Or at worst, tell the window to redraw instead,
eg. window()->redraw();
