           Summary: Dinoshade example from opengl.org renders incorrectly on
                    savage MX/IX
           Product: Mesa
           Version: 7.6
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/Savage

Screenshot

Here is the source:
http://www.opengl.org/resources/code/samples/glut_examples/examples/dinoshade.c
I tried it on HP OmniBook XE3.
It works OK if hardware acceleration is disabled (using software renderer), but
when it is enabled, the result is as in the screenshot. At the same time,
reflectdino example is OK. (all examples can be found here:
http://www.opengl.org/resources/code/samples/glut_examples/examples/examples.html)

Even simpler stencil example from the RedBook leads to the same problem.
http://www.opengl.org/resources/code/samples/redbook/stencil.c
Seems something is wrong with stencil buffer...

Ruslan Kabatsayev, Ubuntu 9.10 reached EOL on April 30, 2011. For more on this,
please see https://wiki.ubuntu.com/Releases .

If this is reproducible in a supported release, it will help immensely if you
filed a new report with Ubuntu by ensuring you have the package xdiagnose
installed, and that you click the Yes button for attaching additional debugging
information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.
