weird pointer 'artifact' in Picasso96/CG64/3D

[cdfr]

I had the same problem.
I was comming from one memory chip on the card. Just by pressing on it a little the artifact would disapear. I guess that the fact that you open your case and move around things into your computer may have put the chip in a better contact position. It may come back as soon as you move your computer again ...  :-o

If I remember well some of the mem chips are on socket.
It was one of these (can not remember which one exactely).
