No, but I can't make that out in the png version either. http://www.turnkeylinux.org/files/images/blog/jpg-vs-png/dru...

Looks like an issue with the original file - it was probably created at a higher res and then down-sampled.

Thanks, that's a good point. I actually stopped noticing that bit of silliness. I just sent Alon, who did an otherwise commendable job slapping together those icons in the GIMP, an email asking about that...
