Description Pierre Beyssac 2008-04-24 15:26:00 UTC 
See the attached png capture:

In red, triangles rendered with glMultiDrawElements() without a display list.

In green, the same triangles rendered with glMultiDrawElements() within a display list. One triangle is missing.

See provided source code.

This is using the R200 driver with Mesa 7.0.3 as patched with http://bugs.freedesktop.org/attachment.cgi?id=16166 from bugid 15670.
