lumen artifacts, fireflies or Flicker?


I am getting this constant Flicker in the bottom of the frame in my Lumen renders, I have turned hardware raytracing off and that did make a little difference but it is still unusable.

I have turned off screen traces, have 16 temporal samples, no hardware raytacing because it was messing up water reflections in the scene.

Is it lens flare?

Is this in editor or out of MRQ?
