[PyQt] PyQt Digest, Vol 145, Issue 25

Got a partial solution that is reasonably workable. Use a custom style
(Clean Looks) and the Gtk 2 platform style library from Qt 5.6. Attached is
a compressed file containing the 2 style files. Works at least with Linux
Mint 17. Should work with Linux Mint 18, Ubuntu 14.04, and Ubuntu 16.04.

In order to improve styling in Linux with a PyQt 5.7 program place
*libqcleanlooksstyle.so* file in
*{your_venv_dir}/lib/python3.5/site-packages/PyQt5/Qt/plugins/styles*, and
place *libqgtk2.so* file in *{your_venv_dir}/*
*lib/python3.5/site-packages/PyQt5/Qt/plugins/platformthemes*. Also you
will need to set the *QT_QPA_PLATFORMTHEME* environment variable to *"gtk2"
*before running a PyQt 5.7 program, otherwise the platform style isn't

Not ideal but at least PyQt 5.7 programs are usable in Linux. One temporary
workaround depending on project requirements is to downgrade to PyQt 5.6,
which doesn't have the severe issue.
