[Qt-interest] Works in 4.53, but not 4.6.

[Freak .]

Hi, recently i have been using Qt 4.53 with Direct3D 10 under Windows 7 x64.
(Works great)

When configuring Qt4.53 I used a "-direct3D" switch to ensure that it
worked, with things like
setAttribute(Qt::WA_MSWindowsUseDirect3D, true);

I'm aware Nokia removed the "experimental Direct3D support" in 4.6, but does
this mean my code will never work with Qt4.6 and above?
I'm not sure what that "-direct3D" switch was actually doing when building
the libraries?

My code compiles but i now have fighting between my MainWindow and the
Direct3D drawing, even though i implemented my own
paint event. Basically i get a grey background, if i resize or use a Qtimer
to refresh the screen i can still see my Direct3D windows being drawn,
but the Mainwindow is obviously drawing on top of it.

How can i fix this behavior?

Is there any fix, a flag or switch that can be set or a way to stop the
MainWin.
Any help on shedding some light on this subject would be appreciated, I'm
sure it will come up again in the future.

Cheers,
Scott.
