Becuase there are various “GUI redraw” issues with Cubase 10 and also people who are using multiple displayes with different resolutions reported issues with displaying Cubase 10 in the right way.
When I stumbled over this Microsoft document I wondered if Steinberg still uses the legacy method (“Win32”?) in their application to scale content on screens or if they already followed the Microsoft path?
Many things written there about issues with GUI especially with high DPI screens apply to Cubase 10 where it fails to correctly scale/redraw.
