This is not the experience I'm getting. I'm running XUbuntu Bionic with i3, and the experience is butter smooth; makes Windows feel laggy and MacOS slow as molasses on the other hand, there are no nice animations, transitions and 3D effects like shadowing; just pixels on the screen; however everything updates instantly.
