Yes this has happened to me. Some suggest using a denser batting like W&N. But when it happened to me I had two layers of batting! A layer of 80/20 and Hobbs Polydown on top of that. I tried changing to larger needles, still the same, then a smaller needle, still happened. Others suggest using a more slippery thread like poly. I was using cotton thread. But I wasn't about to experiment further with it. So I ended up giving up on the minky and went with a cotton backing and no more problem. I think it is just the nature of the beast. Some minky will do that and others won't.
