Hi! I’ve had this display issue with the top menu bar for… years now, across versions, with both Cubase and Nuendo. I never found what causes it. It generally happens when opening the software, and is fixed by re-docking/maximizing the menu bar/window - but it’s a seriously annoying little QoL issue, and I’m surprised that after so many years that this keeps flying under the radar.
This is Nuendo 11, on a 1920x1080 display, part of a three screen setup with different resolutions. All screens are set to 100% scaling in the Win10 display settings.
I’m right here if you need more details or if there’s a known fix (not a workaround, please) for this that I don’t know about.
