I wonder whether there will compositor support this driver, to take advantage in the desktop environment. I had made several attempts to get a smoother desktop experience[1] on RPi 3 -
•LXDE + Openbox on Raspbian + X server
•Xfce4 + VC4 + X server + Arch Linux ARM + USB SSD
•Enlightenment + Wayland + Arch Linux ARM + USB SSD
Although Elightenment on Wayland with OpenGL was the smoothest of them all, it's not usable(frequent crashes with RPi) and since the frame buffer was limited to 2048x2048 none of them supported my 2560x1080 monitor.
Xfce4 + VC4 on Arch Linux is more usable, but is still not as stable as default Raspbian. I didn't see any productivity merits in continuing this adventure and decided to reclaim the memory from GPU to revert into headless[Arch+SSD] for a motion eye setup processing 3 720p camera streams simultaneously with average of ~ 50% CPU on all 4 cores when not watching the feed live(but motion active).
