Since the modesetting driver uses OpenGL, you have to force enable layers.acceleration (layers.acceleration.force-enabled) in about:config to remedy this. The other thing that works is to enable the Intel DDX driver with TearFree. This is on a fresh Ubuntu 17.10 install in the Xorg session but the same would apply to Wayland as well as Xwayland also uses the modesetting driver.
