In case we want to share our context with QtQuick, which one should we pick?
Is there a main context Qt uses for its views (not only QtQuick because
classic widgets use OpenGL too I guess)? Or do we have to share QtQuickView
contextes as they are created?

Here is where we currently are:
- Threading our OpenGL code would currently mean having a thread between
our project and Qt-related code.
- Wrapping OpenGL code in makeCurrent() is not done and is not planned by
the team due to optimizations and refactoring that never has been
necessary. I agree it

Then you need to isolate why it crashes and choose a method to fix it.
Some options:

I'm not sure where to set it, do you mean QSG_RENDER_LOOP is really an
environment variable like PATH on Windows? Oo
As for QQUickFrameBufferObject... I'm not sure how it will work.
Our application creates its own context and has nothing to do with Qt in
the first place. Because of its nature, all

Hello,
I'm currently integrating an application using OpenGL in a Qt GUI where QML
is mainly used. We may need one or even more OpenGL views rendered by our
application.
But as soon as something Qt is shown, the application's rendering glitches
and sometimes crash, even if the Qt stuff is in a sep
