Analyzing song glitch - bug

Hello,

I have a big issue with Rekordbox, that it's reproducing on all 3 Macbook's I have. Macbook Pro (2012, 2015, 2019) with rekordbox v6, I tried all versions. When it's analyse songs, a single one or multiple, Rekordbox add a glitch and broke the song. It's happen random. You can see in my picture how the grid start to not be aligned. I tried with all 3 analyzing methods, normal, performance and power saving. Please advice!
