Rekordbox 5 - Waveform trembling/twitches

I had MacBook Pro 15" 2014  2.8 RAM16 - and everything worked smoothly & perfectly. In April I bought a MacBook Pro 15" 2018 2.6 RAM16 - and the problems started. Waveform - trembling a lot, in full screen mode - it's generally impossible to work. Trembling intensifies when I listen a track in the Preview, or when I press any button on the controller (DDJ-RX).

I downloaded the old version of Rekordbox - 4.5

To my surprise in version 4.5 - no trembling. Waveform works smoothly.

WHEN DO YOU CORRECT THIS PROBLEM ????

(Buffer size in all cases is set to - 128)

Instead of improving the problem - with each new version there are more and more problems !

I have been writing to you for a year now about the problem with "Analyzing Hole".  Almost in every new track, after analyzing - appears hole for a second in the middle of the track. The hole disappears after second play of the track.

Will you ever solve this problem ?????
