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?

I realized I jumped the gun on this question. For some reason it takes a reboot for effects changes to fully implement. After a reboot with Xrender enabled things slowed to a crawl and most of the effects wouldn't work. The only improvement was in the performance of OpenGL games.

For reference, here's the "really crappy graphics driver" on my (cheap) laptop where XRender is smooth and nice and OpenGL is horribly slow: Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

Until F8, it was perfect :/ Currently, garbage often appear on screen at random places if desktop effects are enabled and open gl applications behave strangely when other windows are opened over or under them. I still didn't move on from F8 on my laptop because of this.
