Hi Hilaire,

BitBlt and VectorGraphics have a different idea of what a pixel is. 
These kind of things usually happen when you mix in the same morph stuff 
drawn with VectorGraphics and with BitBlt. Try changing the canvas to 
VectorGraphics: `MorphicCanvas activeSubclass: VectorCanvas`. If this 
fixes the issue, an alternative is to make sure that all these answer 
true to #requiresVectorCanvas.

Cheers,
