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>

Any update on this, I have upgraded to the latest packages for React 19 / Next 15 + all the ThreeJS related packages and I still get an issue

I have the same problem https://github.com/pmndrs/drei/issues/2183

Glad it's not just me @EugenIlchenko

I also have it where the Refraction just drops out and the model renders with a flat standard material

Did you find a solution to this? @AaronLayton

I did not @christianstamati - I ended up pinning the branch for now - it is still on my todo list to update, I figured I would give this Issue a while to see if there was any traction on it or if there were any updates to the package before trying again
