[Interest] QT5, Mac Accessibility, and Spectacle

[steven hay]

Hello,
I am a user of Qt on my Mac, and one thing I use very frequently are window-resizing keyboard shortcuts using a program called "Spectacle." This program appears to use the Mac Accessibility Protocol to move and resize windows around when certain key combinations are pressed. 
With the move to Qt5 from Qt4, this application has stopped working for my Qt apps (I have rebuilt using Qt4 and the functionality comes back) [Note: Specifically, the app I use most is Quassel]. There is an open issue on the Spectacle web site (https://github.com/eczarny/spectacle/issues/529) that has some (very little) information on the issue--but it does indicate the problem may be in the implementation of the accessibility protocol.
Is there any way to figure out what the actual problem is here, so that it can be fixed? I realize this is an issue spanning across a few projects--so finding the culprit may be a bit of a challenge.
