ok, I swear I've heard of this before but I haven't tested it until now. The spawn eggs have a weird graphical glitch when they are dropped in a set of 2 or more. It looks like the spots are revolving around the base eggs... like they are not a part of the egg's sprite. so I made a video looking at the eggs. Single eggs are fine but the groups are glitchy...

Duplicate of MC-1176?

Confirmed with Windows 7-64, AMD Radeon 7600, but nevertheless a duplicate of MC-1176
@ Grum
um... yea I do have an Intel video card. I had no idea that could be the problem @_@
I guess this is a very "popular" problem then?

@Devin: It's not an intel issue. Take a look in MC-1176
Let me guess, you have an Intel 'videocard'? 😃
Unable to replicate this problem on my desktop/macbook.
