Technically not passing all buffers used by a kernel is undefined behavior. We haven't had any issues with this so far on AMD or Nvidia, but it's known to be a problem with Intel and we received a report from AMD that this is a problem on newer hardware, so we need to make this change at some point. Unfortunately there a cost to being correct, about 5% for the benchmark scenes. For low sample counts it's even worse, I've seen up to 50% slowdown. For the latter case I think adjusting tile updating logic can help, but not sure what that would look like yet (it would be just a few lines change however).
