When I open a PDF in Acrobat Reader DC, the field turns black, pixelates, and starts blinking. If I click in a field I can edit, the field will appear correctly, but the moment I navigate away from the field, it's black again. I have uninstalled and reinstalled the newest version on my Windows 10 machine. My problem looks like the attached picture. If there is a solution, I would appreciate some help. Thanks.
