I can see the slight colour error on the left margin of your Linux scan, 
though I had to look very carefully. I did a check with my own LiDE 210 
and could not find any colour distortions - so it might be a hardware 
error, though it amazes me that the Windows scan software removes the 
colour errors.

Perhaps it depends on the sane version? My version is
