This indeed is a nuisance. You can't really have a white line or fill, which you might need for an advanced graphical layout. Or to hide parts of a drawing. The problem probably originates in the automatic switching of black/white lines according to a black or white screen background in drawing mode.
I too wish to a have a true white available. But I guess this issue is not considered as urgent enough to be tackled.
