Brian,
After reading yours, I thought THAT is going to be the fix. It didn't work but I think I know the problem. It was an easy enough shot that I manually tracked with just a mask so there are no corner pins.
So, to recap, I took my layer, which is just a solid. This one does NOT have the shine and that probably doesn't matter anyway.
So, I removed my mask keyframes, along with effects applied, then applied the effects first, then the corner pins back. It remains the same.
Now, I am not even sure I can make it work at all with this setup.
