            Bug ID: 98106
           Summary: Primitive restart should be disabled for Draw commands
                    when GL > 4.5
           Product: Mesa
           Version: 11.2
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: martina.kollarova at intel.com
        QA Contact: mesa-dev at lists.freedesktop.org

Originally reported on #dri-devel by user degasus.

OpenGL spec < 4.5 has a line in the "Primitive Restart" section:

  If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
  performed for array elements transferred by any drawing command not taking a
  type parameter, including all of the *Draw* commands other than
*DrawElements*.

OpenGL spec 4.5 has a modification:

  Note that primitive restart is not performed for array elements transferred
by
  any drawing command not taking a type parameter, including all of the *Draw*
  commands other than *DrawElements*.

The current implementation doesn't take the new version into consideration, and
an additional condition for GL > 4.5 should be created.
