DOF problem Movie Export Matinee

Hi guys,

I’m exporting a clip from Matinee. It’s just a single camera track. The camera itself has a 90FOV and a 2.25 ratio. It also has some minor DOF enabled (bokeh, but also tried circle and gaussian)
All my settings are on Epic/100%

Whatever I try (100/200/300%Temporal/FXAA, HD/HFD/Sequence .png/.jpg/.bmp, 30/60fps) I always seem to end up with a result that shimmers quite heavily.
Disabling DOF and I end up with a exported clip that’s very nice. Anyone any ideas? I have to do something wrong cause obviously DOF enabled in your clips should just work.
