    Hi,

    I have an app I have developed using Qt 4.8, which I am trying to port to Qt 5.

    The app uses almost entirely OpenGL drawing (specifically using compatibility profile in order to ensure that everything works over remote desktop) so the main window is essentially just hosting a QGLWidget and then I draw everything custom inside of there.

    I have a few QGraphicsProxyWidgets I'm using for things like combo boxes and tree views so I can "embed" those into my OpenGL scene.

    However, after upgrading to Qt 5, I noticed that those widgets are not drawing in my application when I try running the application over remote desktop. I tried using gDEBugger a bit to see what OpenGL commands are being issued, and I noticed some shader commands being used, which might explain it since shaders don't work over remote desktop.

    Is there any way to get this working in Qt 5? I am using the "OpenGL" version of Qt 5, not the ANGLE version. ANGLE is not really an option for me, since I have some OpenGL code which doesn't fall under the OpenGL ES 2 specification.

    Thanks!

      Hi and welcome to devnet,

      Since this question might go low-level, I'd advise you to bring this topic on the interest mailing list. You'll find there Qt's developers/maintainers (this forum is more user oriented)
