Antialiasing in FilterPostProcessor causes issues with Ambient Occlusion

There is this globe of darkness around the camera that appears when I set the number of samples in FilterPostprocessor and i have the SSAOFilter attached.

SSAOFilter ssao =  new SSAOFilter(12.94f, 43.92f, 0.33f, 0.61f);
if(settings.getSamples()>0) POST_PROCESSOR.setNumSamples(settings.getSamples());


Did someone else experienced this issue?
