Have you tried to override the settings of the executable? On my machine the window decorations are scaled properly. It is nothing the VM itself can fix. In the Manifest, there are several levels of dpi-awareness, which also affect the scaling of the windows decorations.
Read more about this here: https://docs.microsoft.com/en-us/windows/win32/hidpi/high-dpi-desktop-applic...
In the app bundle, we use the following configuration in the Manifest:
``` asmv3:application asmv3:windowsSetting <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true/pm</dpiAware> <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness> </asmv3:windowsSettings> </asmv3:application> ```
To support both Windows 10 (Update 1703) and prior versions.
