Not at all. I want our developers to have the best experience possible. I just
don't want it to come at the cost of other developers who need to do more than
only use Qt Quick 2. Anyway it seems we've reached a consensus in the other
parts of this thread about a way forwards.

I agree that using OpenGL across the board on windows is perhaps not the best
choice at this time due to the highly variable driver quality and
availability. It may be that for Qt6 we should consider providing an
abstraction at a different level to allow for a genuine Direct3D renderer for
Qt Quick in a similar way that the likes of OGRE offer the choice. However,
that is a far bigger change. Another option would be to have provide
assistance in providing a software fallback in the form of mesa + llvmpipe or
similar.
Have a good weekend,
Sean
