One common place it can happen is on the Planar Transform itself. If you have incoming information outside the immediate frame you might be clipping it if you're not set to Domain:

Hey Jed, thanks for the reply.
I have a rotoscoped shape inside the frame, covering a house number in shot.
As it moves with the planar transform it is as if the matte is moving but not the RGB it if that makes sense.
My feeling is it might be a ram issue as it happens randomly. I am on a Macbook Pro 16 gig ram.
Cheers,
Declan
