Cubase 13 Score - cursor disappears during playback

I’m using Cubase 13 Pro in Win10 Pro.

During playback, in the score “page mode”, the vertical bar that crosses the staves and moves following the playback disappears and reappears (apparently randomly), making it very difficult or impossible to understand the correspondence between the audio you hear and the matching position in the score.

In C12 the problem does not occur (I checked by closing some files in C13 and reopening them in C12 with no other action than playback).

Obviously this is not a major issue for me, as I can easily switch to C12 whenever I need to use the score functions.
Nevertheless, I’d like to know the reason for such a behaviour.
Did I miss something in learning C13?

Hello MarcoRo,
I have exactly the same problem with my Cubase 13 Pro.
With Cubase 12 Pro, the song position cursour runs normally.
It would be really great if someone had a solution to this problem.
Thank you very much and best regards.
