First, turn off "Flatten," which will get rid of the yellow and red peaks at either end.
Second, set Start to 250 or 300 Hz and Bins/Pixels to 4 or 5, so that the display shows only the bandwidth of your IF (in this plot, audio from 350 Hz to 3.55 kHz). Audio frequencies outside these limits don't get through your IF and roofing filters, so don't waste DSP on them.
These comments apply specifically to WSJT-X, but the same concepts are at play in FLDIGI (which I don't use, so can't help you with).
