KDE4 effects Xrender vs OpenGL

[mark.bidewell at alumni.clemson.edu (Mark Bidewell)]

I was playing around with KDE 4.2 compositing settings and I tried
switching from OpenGL to Xrender.  It seems as though my system
operates smoother with Xrender than OpenGL.  Is there anything I
should be aware of using Xrender instead of OpenGL?

Thanks.
