Some questions:

1. Did you build with cairo support and if so what version ?

2. What Qt version ?

3. What does Help > About show Build Info:

4. What version of XPDF ?

5. Do you have a sample file ?

The blendmode isnt translated correctly IMHO: screen -> Bildschirm
(== displayscreen)

This version of XPDF cannot display tranparency properly. Only 3.02,even then it does not seem to support blend modes. Kpdf from KDE 3.57 does.

Yes, must be "Negativ multiplizieren". Will be fixed in the new ts files.
