gamepadAxisEvent floods events
Using a PS4 contoller on Ubuntu, http://doc.qt.io/qt-5/qgamepadmanager.html#gamepadAxisEvent is absolutely flooding events about the values being the same or alternating in short order. Is this intended?
Likely not but that is just a guess. You should rather bring this question to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.
