Xorg.0.log

When DRI is enabled on the ATI FirePro M7740 card (Dell Precision M6400
laptop), some text and images are rendered with artifacts that I suspect are
caused by texture memory issues.  Increasing the FBTexPercent option to 90
causes the desktop background image to also suffer the same effect.  Changing
between EXA/XAA has no effect.  ColorTiling on/off has no effect.  Only turning
off DRI will banish the artifacts.
