Waveform flickering rekordbox 6.0

Hi
I was wondering if someone else is getting a waveform flickering during playback in rekordbox 6.0 in a Macbook Pro.

Flickering occurs randomnly 2 or 3 times per minute. It dosent affect sound but its quite annoying becouse it feels software is somehow unstable.

I try de following setting configuration and it occurs in all of them:
- Medium and Fast waveform refresh
- Discrete and integrated graphics card
- macOS drivers and nVidia drivers
- Video option enable and disable

This problem wasnt present in previous version of rekordbox

Here is a clip cropped 1 second before and after the flickering occurs at the waveform visualization box:

How can I solve this?
