--- Comment #1 from Alexandre Julliard julliard@winehq.org --- Probably the app explicitly specifies that it doesn't support high DPI, we recently started respecting that setting. Ultimately such apps will get pixel-scaled, but that's not implemented yet.
You can override the app by setting its execution options, something like this:
[HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\your-exe-name-here.exe] "dpiAwareness"=dword:00000001
