We've seen long-established characters changed to a different race or gender or sexual preference or some other trait just to make the content more "inclusive", even if it makes no sense within story lines or established canon. Or we've seen new characters created with a trait like their gender, race, or sexual preference as their main defining characteristic, solely so focus can be put on it, and the rest of the character pretty much ignored.
To be fair, there's also still a non-trivial amount of white-washing going on, too. The most recent and accessible example for the Slashdot audience would be casting Scarlett Johansson for the Ghost In The Shell movie.
In fact, I am somewhat curious about this list of movies that fit your criteria, as I can easily rattle off several whitewashing examples from recent movies off the top of my head, but I cannot think of that many where the reverse would be true (though there are some).
