Yes, you have to restart for it to take effect. BTW, I think only
changing gfx.canvas.azure.backends is necessary,
gfx.content.azure.backends can remain at default setting.

The only negative impact could be slower performance in some cases. But
it does provide better performance in other cases, so it depends. And of
course, not crashing is a benefit. :)
