Happens both with the latest 5.3 and 5.7.

Just after it finishes writting the PPM, the low-res 'grid' is drawn,
but the southern 10-15% is missing. When you change the view angle you
are looking at a blank screen, when you finish it redraws the hi-res
'polygon' version ok.

-> Resizing the viewing window causes the above error (& crash).
