Nick, you'll get this effect as soon as any scaling is involved. 
The stems
can be displayed only in integral numbers of pixels.  At normal
magnifications this is either 1 or 2, depending on where the scaled
line falls relative to the pixel grid. To avoid this type of 
distortion you
need to view at 100% with resolution set to the screen resolution
(usually 96 pixels/inch), or 200% with resolution set to 192 
pixels/inch,
etc.
