If *after* generating a gif you change the gif size (bigger in my case) the new gif has the sunglasses appear in the same place. But if I change the size first and then generate everything work fine.
I immediately knew what you meant, because I ran into the bug while testing earlier today and apparently forgot to file it. So thanks for reporting - I've filed it now properly and should have it fixed soon.

Hope I explained it right
