I am getting a flickering when trying to use a bloom effect with mipmapBlur. As soon as I turn of the effect nothing flashes anymore.
I have tried varying all the values here but nothing is working. Any ideas?

 <EffectComposer>
        <N8AO aoRadius={0.15} intensity={4} distanceFalloff={2} />
        <Bloom
          luminanceThreshold={10.5}
          intensity={0.85}
          levels={9}
          mipmapBlur
        />
        <ToneMapping />
</EffectComposer>
