Dear all,
Getting this warning in every Project How should i solve that?
Warning: Setting a new default format with a different version or profile after the global shared context is created may cause issues with context sharing.

@Dev-Tyagi Which Qt version?
Do you get this warning even with a fresh project created using wizard without any additional code from you?

Dev Tyagi

@Dev-Tyagi OK, don't know what causes this warning. You can search on Internet for it, maybe you can find more. Also, you could try to update to more recent versions.

I don't know what causes it or how to solve it. Just find out where it comes from:

void QSurfaceFormat::setDefaultFormat(const QSurfaceFormat &format)
{
#ifndef QT_NO_OPENGL
    if (qApp) {
        QOpenGLContext *globalContext = QOpenGLContext::globalShareContext();
        if (globalContext && globalContext->isValid()) {
            qWarning("Warning: Setting a new default format with a different version or profile "
                     "after the global shared context is created may cause issues with context "
                     "sharing.");
        }
    }
#endif
    *qt_default_surface_format() = format;
}

Qt Design studio

Isn't that just for design? So the warning is from the studio itself?

I've never used that studio by the way, hope others can have some ideas.
