Flickering DOF and AA in rendering

Development Rendering
1

This is a project we already delivered to a client, but now we want to make a sequence for reeling purposes. Problem, Lots of flickering.

I already can pinpoint this is being caused by TemporalAA, although, i have no idea how to fix it.

No matter if the performance is impacted, we will be rendering the sequence anyway.

Any ideas how to fix the flickering?

Sadly it does, all reflections go away when switching to other AA methods, and, since there are above 1000 materials, reprocesing everything for forward shading isn’t an option.
