main.qml has a button on the upper left of the UI, used for switching between the two QML files.
On QNX, run the app.
While monitoring the output of the top command, press the button rapidly 40-50 times.
You will notice that after the entire operation, you will notice that the free memory is significantly less than before performing step 5.
Repeating steps 3 and 4 above, w/o performing step 5, does not result in a memory leak.
