Disappearing then reappearing chunks of track in Cubase 13

Hi All, I’ve just upgraded to Cubase 13 and it has some nice new features. However, when I scroll my cursor over the tracks to edit, they sometimes disappear momentarily and I can see my home page underneath where it’s disappeared. Then it comes back again. I don’t lose any data, but it’s a bit offputting and feels a bit unstable. I’m on Windows 11 with a 12Gb RAM and 100Gb memory, and Cubase 11 and 12 are fine. Has anyone else noticed this and I wonder if/how it will be fixed. Cheers.
