Oh the jaggies only show up when I rescale(up) after creating the globe.
I got the original logo from the forums header.
So using your advice, to increase way above needed size(1600 x Whatever it was), I did that, with the original 1st.
Then I got rid of the transparency.
Then Filters > Render > Spinning Globe(without optimizing for gif first)
And this is the result(I can shrink it later)
@Cliff S. Try this TF logo. It's one I created as a vector so it should be really sharp. It has a transparent BG so you will need to add one.
