I've had the same problem and managed to get around it by setting the internal pad
GridBagConstraint (ipadx,ipady) whenever I use a subclass of Canvas. The problem
seems to be that Canvases are drawn in areas of size (0,0).
I'll bet you could also override minimumSize() or preferredSize() in your Canvas
subclass to get the same result.
