On some songs the visual waveform seems to be delayed along the songs lenght slightly. Cues, grid and audio are aligned but the visual is off.
Attachments have examples of a few songs like this. Near the end of the song the visual is delayed.

If you set those in Serato and then also imported from Rekordbox (which you mentioned), that could cause weird results.

Try Reanalysing Waveform and see if that fixes it.

Please install this beta, then select your tracks (or at least the ones where you noticed the drift problem), right-click and choose 'Re-analyse Tracks' then click 'Rebuild Waveform'.

Once that's done you should see an improvement.

Let me know how it goes!

Seems to be fixed now in 2.17! Have browsed through a bunch of tracks now and haven't found one with this problem. Will report again if it comes up

Whoop! Great news, thanks!
