It is in the exact same spot, in the same orientation, and doesn't more or change. It looks like a question mark on every frame. Here is a frame showing location - to the left side about half and inch from the edge, and about an inch or so from the top. Also a close up of the squiggle.

I also attached an image showing the dark side that happens. I removed the insert and triggered the shutter, but I'm not sure what I'm watching for. Can you clarify that last part? (Sorry, newbie here.)
