    Description

      when GL_DEPTH_TEST is enabled, text rendered by renderText(x,y,z,text) is obscured by an object even if the text is in front of the object. When the same code compiled in Qt-4.8 depth test works as expected. See the attached sample code and screen shots (the left part of the square is behind the text).

      This might well be the same bug as QTBUG-31156, but this example possibly pinpoints the problem somewhat better.
