IMHO you should not use Qt Quick 2D Renderer as an argument unless it were
available in the open source package, but you could argue that there is
mesa software render support in 5.5. What's the difference between the 2?

export QMLSCENE_DEVICE=softwarecontext
export QT_OPENGL=software

It would be nice if the article would mention that.

On the windows side, Qt Quick 2 applications have issues with the OpenGL
dependency since Microsoft doesn't provide an implementation, it's up to
graphics drivers. If you don't have a decent driver or version it will
fail. Also Remote Desktop connections doesn't work. The dynamic opengl
implementation in 5.5 solves that. Up until now the Remote Desktop issue
kept my application from migrating.
