Public bug reported:
Firefox has choppy scrolling/tearing on pretty much any web page with
the default settings on Intel Graphics. 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.
