mixing openGL and native painting

hello everyone!!!

i'am trying to make gles2 and qt work together.

i have managed to compile qt with GLES2 and then qt/3d.

but i have problems with mixing openGL and native painting.
so i can't normally program 2d UI in my 3d application with help
of qml+qt/3d.

examples of this issue:
hellogl_es2.pro(have no deal with qml ot qt3d but I think this is the same issue):

allmost all qt/3d applications won't work. example (moon.pro):

but all qt-quick-3d projects without 2d contetnt run perfectly:(basket_qml.pro)

qt-quick-3d projects without 2d contetnt run but with artifacts.
exploring of this artifacts made me think that 
when i click native qml element it an only it daws normally, but other 
native qml elements overpainted by opengl content(Item3d).


i am using Beagleboard OMAP3530, Qt 4.8 (tryed also 4.7.3).
EGL version 1.4. all SGX demos run correctly.

have any ideas? thanks!

    We have checked the QGLWidget + 2D painting through hellogl_es2 and textures demos. They are working on Qt 4.7.2.

    From the screenshot, OpenGL + painting seems to be working? On the hellogl_es2, there is the 3D Qt logo rendered by SGX. On top of this, the FPS information text is drawn by the raster paint engine. 

    Regards,
