[PyQt] PyQt 5.12 broke QtAwesome

[Carlos Córdoba]

Hi,

We have a small library called QtAwesome to use iconic fonts in PyQt 
applications:

https://github.com/spyder-ide/qtawesome

that we use in Spyder to display FontAwesome and Material designs icons 
in our interface.

Unfortunately, the release of PyQt 5.12 broke it somehow because our 
icons look corrupted now, as can be seen on this issue

https://github.com/spyder-ide/qtawesome/issues/113

To verify that this is only a problem with PyQt and not PySide2, you can 
run our example file

https://github.com/spyder-ide/qtawesome/blob/master/example.py

with one or the other installed in a virtualenv and you'll see that the 
problem only appears with PyQt.


Thanks for your help,
Carlos
