            Bug ID: 99842
           Summary: GL_ARB_transform_feedback2 on i965 gen6
           Product: Mesa
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: mail at felix-potthast.de

Mesa supports GL_ARB_transform_feedback2 only for gen7+, and i wonder what the
reason is, since the functionality is present in OpenGL ES 3.0 which is
supported by gen6. It sadly prevents my Chromium/Firefox from supporting WebGL
2.0, since they use an OpenGL context instead of an OpenGL ES context and
therefore depend on this extension to get required transform feedback
