Multiple monitors with different scale factors

The application must enable per-monitor DPI awareness in order for the region selection to work properly on a multi-monitor setup where not all monitors use the same scale factor.

It is recommended that to be set in the application manifest:

<?xml version="1.0" encoding="utf-8"?>

<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1">

  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">True/PM</dpiAware>
      <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2, PerMonitor</dpiAwareness>
    </windowsSettings>
  </application>

</assembly>
