[Development] QGLWidget creation with non-visible parent

I would like to ask your help in some Qt 5 matter. I think it's somewhat
related to QTBUG-31451, but not sure.
When I create a QGLWidget with a parent which not yet visible, then it
seems to fail to compile shaders although QGLContext is valid( at least the
isValid function returns true).
e.g.: there is a tab widget, which is visible, and from code we add another
tab, so that it contains a QWidget and inside the QWidget, there is a
QGLWidget( yeah, i kno w it's messed up, but that's it). So when we create
the QGLWidget with the QWidget parent, the QWidget is not visible, and - as
far as i discovered - it has no window handle.
It worked fine, in 4.8, and i compile with msvc 11.0.
My question is that is it a bug or did I miss something? Would someone
point me in the right direction?Should i post my findings to the mentioned
bug thread or create a new one?
