Why can't I use OpenGL ES 3.0 in Qt?

[Stefan Monov76]

I set a QSurfaceFormat on my window, and this surface format has "3.0" set as its GL version number. Also, in main() I enable OpenGL ES mode, like this:

QGuiApplication::setAttribute(Qt::AA_UseOpenGLES);

This means I'm requesting a GL ES 3.0 context.

The ANGLE docs say (in a table near the beginning) that GL ES 3.0 -> D3D 11 API translation support is implemented. And my system supports D3D 11 according to dxdiag.exe.

But when I launch my app, which contains this QML code...

Text {
    text: OpenGLInfo.majorVersion + "." + OpenGLInfo.minorVersion
}

... I see "2.0" is displayed. Also, using the method I described here, I've determined that the maximal supported shading language version on my PC is "100" aka 1.0.

At the same time, from this Qt blog post I know that Qt supports GL ES 3.0 apps.

So why can't I use OpenGL ES 3.0 in Qt?

I got a working solution (in comments) here.
