Rekordbox jittery today

Currently I'm running the latest version of Rekordbox 5.2.3 and noticed that the waveform is jittery as tracks are playing. Never noticed this before. My laptop is a MacBook Pro running Sierra 10.12.3. I checked out other software's and none are showing this issue. Went through and cleaned out the unwanted junk in my computer which hasn't resolved the issue. Music plays fine, just the jitter of the waveform is a bit annoying. Any ideas of what more I can do to resolve this?

Thanks
