Is it the problem with image creation ? i have created this sprite image with image magic from multiple images using following command.

montage -tile 1 -geometry +1+0 -gravity Center -extent 280x212 1.png 2.png x.png

You need to set the background to white (using "Pick Background"), then it works for a lot of the image. Unfortunately, the heavy jpeg compressions blurs the boundaries from one part to another for the top few sprites

Setting background worked. Thanks @jakearchibald
