qmlglsrc on Windows

Hi,

I've touched grabqml
<https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/tree/master/tests/examples/qt/qmlsrc>
example
on Linux. It works slightly better. Now I can see a completely black output
window ("OpenGL Renderer"). I've got this error message:

Xlib: extension "NV-GLX" missing on display ":0".


I'm pretty sure that this time it's not a GStreamer issue at all. It seems
something wrong in my environment:

Ubuntu 18.04.2 LTS
GeForce GTX 1050Ti
GNOME 3.28.2
GStreamer 1.14.4

But any other Qt/Qml/Qt3D graphics applications work fine. Even qmlsink
<https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/tree/master/tests/examples/qt/qmlsink>
example works.
I'm relatively new Linux user. What do you think about it?
