Currently I have put that workaround to cope with Gtk's hiDPI bug (fixed DPI=96) in login.conf(5), but I think there should be some logic in one of KDE's or Qt's startup scripts to set it if Qt is in HiDPI mode. Which one?
BTW Gtk2 apps work fine, only Gtk3 apps are way too small (or way too large iff run with an integer scale of 2). In contrast, GDK_DPI_SCALE can be set to a floating point number, i.e. I can compute it to be GDK_DPI_SCALE=myHiDPI/96.
Thx in advance for any suggestions.
