Hello

I've done a game that uses OpenGL. For Symbian, Meego and desktop I use Qt for 
the device initialization and then I use raw OpenGL calls.
I am using Qt4 with no problems and now I have converted it to Qt5. The problem 
is that in Windows the rendering is displaced. A small rectangle with the upper 
left corner of the game appears at the low right corner of the Window. If I 
maximize the window then the rectangle may be about one quarter of the screen.

In Linux the display is perfect in Qt4 and Qt5. Also the game runs with pure 
OpenGL ES in Android, iOS and BB10 without problems.

I've tried Qt 5.2 MSVC2010 32bit OpenGL and Qt 5.2 MinGW 32 bit and it fails in 
both. In Qt4 the OpenGL version is 4.3.0 and in Qt5 is 2.1.2, in both cases the 
vendor is NVIDIA Corporation and the renderer is GeForce GTX 560 Ti/PCIe/SSE2.

What can I do to fix it?

Thanks in advance
