I was told Sun China is working on an updated libdri (DRM) which may provide the official fix. You can use the Indirect rendering method to get around certain issues. This issue doesn't appear on older Intel GMA (i.e. Intel 845G series) hardware using OpenSolaris 2008.05 using the default Compiz or Compiz 0.7.6.
For a wider scope on the graphics front, I've mentioned the move to Mesa 7.0.3 which was done over at Blastwave.org a few months ago for an OpenGL software fallback when the graphics hardware (pipeline) didn't support the newer OpenGL 1.5/2.1 extensions (or had issues in the hardware acceleration). This worked for us for the time being. This is available with both 32-bit/64-bit libraries to provide the OpenGL 2.1 framework. I'm hoping to see things fixed with the Intel X3100 issues by SXCE b92 on the Toshiba Tecra series. ~ Ken Mays This message posted from opensolaris.org
