I think computing optical flow remains a major time bottleneck. Any attempt at temporal coherence would be great, and I'm sure there is some attempt on Messenger, but it really only works well for the last style transfer filter, all the way to the right in the app, and that one only really looks great in well lit scenes. Also, the phone seems to heat up a lot.
