I've just noticed that in my system (debian GNU/linux stretch) kdialog and 
okular are based on an older Qt version:

solitone@alan:~$ kdialog --version
Qt: 4.8.7
KDE Development Platform: 4.14.26
KDialog: 1.0
solitone@alan:~$ okular --version
Qt: 4.8.7
KDE Development Platform: 4.14.26
Okular: 0.26.1

While kate and kmail, for example, that don't have the issue, are based on Qt 
5.7.1 and KDE Frameworks 5.28.0.

So the problem seems related to the version of Qt, where perhaps HiDPI support 
on version 4.8.x wasn't so mature?
