Well, actually not solved per-se, but once you know what it is, you might be able to live with it.
The radio is not malfunctioning. The sdr part of it controlling the rf-gain is rapidly changing, which is much more active as your strong signal changes as you move / wave. The weaker signals don't have as big a ramp-up/down rf-gain change going on.
Knowing this allows me to ignore it, since it's not really broken - just acting normally. But I only use handhelds and maybe for some mobile applications this might be an issue. So now that you now, embrace it!
