Some last notes:
There will be a final Cubase 10 maintenance update as well. The release date is not set yet.
If you are still Windows 7, please be aware that Cubase 10.5 only supports Windows 10 (versions 1809 and 1903) as communicated in summer.
Improving the situation on HiDPI screens on Windows has a high priority at Steinberg. Unfortunately there are no perceivable improvements for the users in 10.5 yet.
seems they are trying to find the solution for it
