Image recognition + visualization = issues
When turning TESTAR visualization on (green and red dots), the image recognition fails to find the action, at least the first action after turning the visualization on.
Not much we can do about that, unless we can take new pics of the buttons after turning on the visualization.
Check the status of the widget recognition protocols to determine if this issue persists and how to change the Spy painting order to remove the dots before taking the screenshot of the widget.
This was fixed in #395
To avoid TESTAR taking widgets screenshots containing green and red dots when the visualization is on, we clear the canvas just before taking the screenshot
