Graphics Glitch when using QmlView class, but no glitch when using qmlviewer binary

On a project of mine I've a graphics glitch when using QmlView in a 5liner-main.cpp.
If I execute the same qml-file with qmlviewer there is no such graphics glitch.

The whole project can be found here:

If you investigate into the bug issue you may want to checkout the bugreport1 branch to get a shorter version of the qml code.

On the attached screenshot you can see the graphics glitch on the left side (QmlView) and no graphics glitch on the right side (qmlviewer).
