            Bug ID: 101338
           Summary: Mesa software rendering draws incompletely on
                    Raspberry Pi
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: lloyd.wood at yahoo.co.uk
        QA Contact: mesa-dev at lists.freedesktop.org

I'm using a vintage Raspberry Pi model B (256MB) with its relatively new PIXEL
1.2 distribution.

PIXEL does not support hardware opengl acceleration, and you can't turn it on
in the configuration dialog, so, using stock software Mesa OpenGL.

sudo apt-get install geomview
sudo apt-get install savi
geomview -run savi

on the Pi should generate a blue and yellow texturemapping Earth sphere in the
Geomview 3D camera window. It does not, drawing only a partial sphere, badly,
suggesting that there is a Mesa software bug here. (SaVi and Geomview are both
twenty years old, and were doing texturemapping on things far less powerful
than a model B, long long ago.)
