I am running a QML application and using X11VNC to remotely view the output. When the QML application uses QQmlApplicationEngine, I am only able to see 2-5 frames per second on the VNC viewer whereas when I use QQuickView, I am able to see 8-10 frames per second.
Since QQmlApplicationEngine is newer than QQuickView, one would naturally assume that it is more powerful. What could be the reason for the behavior I am seeing?
