(In reply to Artem S. Tashkinov from comment #5) > I'm perfectly fine with this configuration not being supported but is it too much to ask to make the browser show a big fat red warning if the user enables these options? There is already. If you open `about:support` you are being told exactly that. And using hidden env variables is even more "I know what I'm doing". Sorry, but there's no way that we can check for certain combinations of unsupported features on specific hardware/drivers. Not even remotely. There's just way too many of them.
