The `sample_disk` returns samples inside a disk of radius 1 which was spanning 2 pixels. The blackmann-haris filter has not much energy at the edge of the filter and since we don't importance sample the filter, we have very low weight samples at some time steps. Improve this by biasing the distribution towards the center. This is a temporary solution until we have proper importance sample of the filtering function for this case. Fix #123630
