Unfortunately libkscreen based in kdelibs4 is unmaintained so this bug won't be fixed by use (you're using code that is 2 years old). I suggest you update to a version of okular based in KDE Frameworks 5, hopefully the bug won't be present there and if it is, that is something we can release new versions and fix. As a very crude workaround you can remove the file /usr/lib64/kde4/plugins/kscreen/KSC_XRandR.so that will most probably fix Okular, but I can't guarantee it won't break other stuff.
