Did you resolve this problem?
We have a near identical issue with our Windows 10 tablet.
It looks to me that Windows is not using the (PDM) optimal text size, which is the Windows default of 100%.
Take a look at this guide How to Change Font Size in Windows 10 « Windows Tips
If i adjust this value to more than the recommended 100% on my laptop, PDM will start looking like in your image.
PDM doesn't seem to support this dynamically.
