I have to correct a mistake: I did get compton + uxa with xfce4 working tearfree on a 4k monitor. I used this conf file
http://duncanlock.net/blog/2013/06/07/how-to-switch-to-compton-for-beautiful-tear-free-compositing-in-xfce/ with the glx backend. On a different note: I was very much impressed by wayland/weston. Following these instructions https://github.com/DragonFlyBSD/DeltaPorts/pull/123 one gets a teafree smooth graphical environment. No apps apart from a terminal but looks promising. I wonder if the xwayland module would allow run the usual xorg applications? The xwayland module did not load; complained about the missing X11 socket.
