Outline introducing lighting changes to my scene

I have a piece of code that using the outline conditionally as shown below.

      {highlight ? (
        <EffectComposer multisampling={8} autoClear={false}>
          <Outline
            pulseSpeed={2}
            selection={[myMesh2]}
            visibleEdgeColor="white"
            edgeStrength={100}
            width={1000}
          />
        </EffectComposer>
      ) : null}

The outline behaviour works correctly but it's introuducing weird lighting behaviours. The first image is before it triggers, the second image is while it's active and the third is disabled after being triggered at least once. Does anybody know what the cause of this is? This is the only post processing effect that's being used.

Reproduce el fragmento condicional de EffectComposer y Outline y compara la iluminación antes de activarlo, mientras está activo y después de desactivarlo, usando las imágenes adjuntas como referencia. Se considera terminado cuando se haya aislado la causa del cambio de iluminación y la iluminación de la escena se mantenga constante al alternar el efecto.
