Waveform issues on v6.6.7

Hello,

I am having issues with the quality of the waveform when I analyzed my tracks on v6.6.7, while on Rekordbox v5 it looks slightly better.
Here, see for yourself:

v5:
v6:
(I know the zoom levels don't match, but the red waveform seems more low quality in any zoom)

Also, on CDJ2000NXS2 the waveform glitches while running.

I think I messed up the Rekordbox settings. So, any help is appreciated!

Thanks.
