Edit: The important bit here seems to be to analyze which of them spends more time in software-fallback state. Also another important thing is why it does that. Does QT possibly use excess features whose dropping would reduce the time spent in software-fallback state but have a negligible impact on the user-friendliness of the UI? This is what I meant by bloat.
