[PyQt] QDialog (and others) not resizing on PyQt 5.10.1 PIP install

[Marko Luther]

Mac OS X 10.13.3 , Python 3.5.4, Qt 5.10.1 / PyQt 5.10.1 installed via PIP "PyQt5"
With the attached script resizing works for Windows, but not for any other of the options incl. QDialog.

I downgraded to PyQt 5.10.0 and with the same code the QDialog resizes again as expected.

Any idea? Is this a Qt problem?

Thanks,
Marko
