I assume you mean with the lensing body being the rapid rotator, not the lensed body. The answer is that we've never observed what you are asking about, and probably never will. We do stand a chance of observing some Lens-Thirring effects when we can see detail slightly smaller than the event horizon of Sgr A*, but that will be a lot more complicated than "a break".
