Erratic playhead/window movement

Hi

In Cubase 12 (pro), while playing, at certain zoom levels the playhead/window moves slightly but erratically left/right.
But not when zoomed in a certain amount or zoomed all out.

I always use CTRL+mousewheel to zoom in/out.
For testing I tried zooming other ways = same behavior.

Let me know if I should try or investigate anything

Here’s a gif giving you an idea of it

Yes, I have the same problem.
