It looks like the Animator is firing an event that is invalidating my "image" JPanel.

Yeah, that's what I was guessing  It should be straightforward to track down -- just breakpoint the invalidation code and see where it's getting called from. I've seen this sort of thing before, and usually it's a mutual parent being invalidated, which invalidates the other children.
