I've noticed that there is a big difference in the quality of the image displayed between IE8 and Firefox on my computer. The IE8 image is closer to the original, the Firefox image is coarser. Is this a general problem or just me.

The firefox image has a green tinge on the edge of the cloud, it is there on both Firefox 3.6.6 and the beta of 4.0.
