Colorchange Pro DC

When opening a PDF in Acrobat Pro DC, all colors change a bit. But when I move the PDF-window over my screen, the colors change to the right tone. One I release the mousebutton and position the window, the colors are off again. Most noticeable in red, and not happening in reader DC.

For example: In Illustrator I made a rectangle in red CMYK (0,100,100,0) with 20% transparency. In Illustrator and reader DC the color is (almost) the same. But in pro DC, it's more orange-like.

All program's are set on CMYK Coated FOGRA39 (ISO 1247-2:2004). Any suggestions what happens?
