WPF control fixed too

I have found the solution for WinForms application.
To resolve this problem you should add to your project a manifest file with following attributes:
Code:
  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
    </windowsSettings>
  </application>

Here is a very simple test file (text and 1pt rectangle):
GDrive ClarityTest.pdf
From onedrive

and result for WPF control and OneDrive (windows DPI is 125%).
ClarityTest

If you zoom in, you can see that is uses ClearType (colored subpixel antialiasing) and WPF control - no. I found that Chrome also doesn't use cleartype, but at least it works correctly with windows scaling:

Is there any way to improve text clarity when downscaled?
See attached image. WPF PDFviewer is at the top, and at the bottom is the same document loaded in WPF browser control (using Adobe ActiveX).
Text clarity problem

It looks a little better when Windows 10 scaling is set to 100%

But still, worse than Adobe.
