Panfall out of sync with signal

using SmartSDR v1.3.8.126 The top half of the panfall screen keeps going out of sync with the bottom half. When this occurs the bottom half seems to be on frequency and showing a waterfall trace consistent with the signal being received however the top half of the display will show no signal on that frequency.

Didn't notice this on v1.3 Is this a known issue and if so is there a fix? Changing bands fixes things for a few minutes but then the problem crops back up. 73 Bill AA7XT

    I have a similar problem which I see on 6 metres I haven't checked on other bands).
    I  hear a signal but the trace on either the waterfall or Panadapter is up to five seconds behind. I have been looking for an explanation but so far, have not come up with one. I don't know if it is the same phenomenon but after a station has stopped transmitting, I will see a ghost image that comes and goes but has an apparent strength which almost fills the screen vertically. Neither of these occurred prior to the latest update.

    I had the same problem with my initial install of 1.3.8.  I thought it was a driver problem with my graphics card (I've been fighting those), but after doing a factory reset and a clean reinstall of SSDR, the problem vanished.

    Just loaded update and about 2 seconds behind realtime for panfall...really makes pileup finding a problem.   Hope next upgrade or intermediate fix to this soonest.

    Carl,
      Do you mean that the Waterfall lags the panadpter, or the the Waterfall lag the 6x00 RX audio or the Waterfall RX audio from another radio ?? I do not see lag in the waterfall here on my 6500.

    No they seem to be about in sync but about 2 seconds behind keying.  Audio is okay just that hard to spot working frequency of split dx operations.

    Same issue here on my new 6300. Isn't there all of the time but it does make pile up searching very difficult on cw. Hope a quick fix is found.
