getframe didn't capture my axes properly

why getframe function makes a strange behaves when I used it in my GUI ?

I call it to capture the plotted animation on my axes in the following GUI:

getframe(handles.myAxes)

but when I combined these frames in one single video file using VideoWriter this is what I get !

you can notice that getframe doesn't capture my entire axes but a portion from it plus some area from the container panel, how to fix this issue ?
