Perhaps it's obvious to everyone but me... what's wrong in that screenshot? The dithering on the background?
It has major artifacts when moving windows and text that hasn't been refreshed in a bit gets increasingly blurred out to the point it is unreadable. A description of the problem can be found here: http://unix.stackexchange.com/questions/248223/antergos-ati-driver-issues "no window effects that I could see. I checked in system settings and realized it was running with Xrender instead of OpenGL, but when I tried to change it I started getting weird artifacts, supersaturation, and odd glitches. Almost all fonts became impossible to read."
and what has lead my here is documented on pages 115 and 116 here: https://bbs.archlinux.org/viewtopic.php?id=79509&p=115
