Screen-Shaking Issue When Using Matinee [Repro]

Hi . I am having a Postprocessvolume (not unbound) which I am inside, sometimes … but even if I disable it, there is no difference. Apart from that I don’t know if there are any buttons to switch between global postprocessing and per camera. Playing with the PostProcessWeight and the Intensity does as well not make much of difference.

The cameras are all spawned by the sequencer.

Are there any other switches that would make the difference?
