Wait, the non-OpenGL renderer for Qt Quick was commercial-only? You literally had to pay them $$$ if you wanted to develop a modern Qt app that actually worked if OpenGL wasn&#x27;t available or functional (which it far too often isn&#x27;t)? That&#x27;s ridiculous. And even now it&#x27;s only available under the GPLv3, which means that if you need to use any non-GPL-compatible code you have to pony up - and also means that distros probably can&#x27;t safely ship it.
