On FFT mode especially on lower frequencies, the Lanczos-interpolated part should look like this:
musical spectrum of 50hz
where a 50Hz pure tone is played, as shown in a post on HydrogenAudio forum

But right now, it looks wrong (it might display multiple Gaussian-like peaks within very narrow frequency range surrounding actual peaks) as screenshots of this component show

Sorry if I confused you
