--- Comment #19 from langkamp at tomblog.de ---
Also have HD 7950 on kde 4.11 (opensuse factory+kernel 3.12 and graphical stack
from git via pontostroy repo)

- opengl + raster = very fast, seldom small graphical glitches
- opengl + native = fast, no glitches so far
- xrender + raster = very fast, no glitches so far 
- xrender + native = very fast, permanent huge glitches
