    Description

      Texts are drawn even when it is behind of other objects.

      This might be related to QTBUG-31156 but the patch for QTBUG-31156 doesn't solve this problem.

      The problem doesn't occur in Qt4.8.x. See the image below.

      How to reproduce :
      Use the attached sample project "hellogl_with_bug.zip".
      Rotate the cube so that the text goes behind the cube.

      Note: The sample project "hellogl_with_bug.zip" is from QTBUG-31156.
