Switching Qml VideoOutput source does not work properly until resizing the window

When switching two random noise generator sources for VideoOutput, the output stretches one pixel of the generated source to the whole video output. Resizing the window fixes the output window.

Steps to reproduce:

• Run attached sample
• Observe noise generated video working as it should
• Press CTRL+A to switch the noise source
• EXPECTED: New source is properly shown
• ACTUAL: Top left pixel is stretched to whole video output view
