Issue with sliding AO shadows with movable lights

Video showing the problem

I show an issue i have with movable lights and some AO shadows that seem to slide around and look bad. Optimally i want to have the same effect (just without the sliding ofc), but with stationary lights. But can’t figure out how to both get some nice ground shadows + nice AO that look realistic.

If you have any good resources to look at for achiving this (other than the obvious epic documentation which i already looked through), then please post. Hope for some good specific suggestions on what to tweak to get better results.

Just tested it with 4.13, and while i haven’t tested all setups, it seem that something has been improved. Im gonna close this question for now unless someone can still reproduce it.
