In the window called "Text After XOR Test" there should be two
composite components, at the bottom of each component the green text
"Test passes if this is green!" should be visible.
On the top component this text should be green on all platforms.
On the bottom component it is possible that on non-Windows
platforms text can be of other color or not visible at all.
That does not constitute a problem.
So if platform is Windows and green text appears twice or on any
other platform green text appears at least once press "Pass",
otherwise press "Fail".
