I've been trying for 2 months now...

That is because your GNSS is being spastic about sending sky data.
There is no right answer, short of fixing the receiver firmware.

I do have some ideas for after the release to add a lot of latency and
reduce flicker.  My guess is it will have to be an optionas the extra
latency will annoy many.

You can thank NMEA 4.11 for that.  It has to do with the way the
receiver dribbles out the sky data.

gpsmon is dead to me.  Way too many bugs, it wass never intended as anything
but a developer tool, and never got that right.
