You should try to comment on the GItHub issue to see if you can get more details of how it was done ?

Got it to work. The only way I got it to work is to launch from command line. ex: gammaray --probe PROBE_OF_CHOICE PATH_TO_QT_EXE\qt_app.exe.

And of course the probe config must be the same as the app's build config. For reference, my environment is Windows 10. GammaRay on Qt 5.6 QtQuick 2.0 apps.

Thanks i'll try that
