Transparent objects being rendered in the scene become brighter as if there is an extra light source

After adding the effekseer runtime to a scene transparent objects that are not part of the effect begin to flicker when on the edge of the frustum of the camera. It seems to be an issue that persists even when an effect is not playing and seems to alter the brightness/color values of the objects. Replacing the material of the object with a meshBasicMaterial or a shader material does not seem to solve this issue. Completely removing the effekseer runtime fixes this.
