Do I understand this correctly, you downgraded PyQt, but kept the Qt version?

And you're not using any hints, just switch the type?

Fiddling with these hints _is_ awful, since they're handled in different os 
levels, some by Qt itself, some below, and they're highly system dependent.

On Linux (KDM), all types are resizable, but Popup, Tooltip and Splash.

Python: 3.4.5
Sip: 4.19.7
Qt5: 5.10.0
PyQt5: 5.10
