I am doing some very basic drawing of triangles in OpenGL, but I am
seeing strange rendering errors. When I draw a textured square (two
triangles) part of the square is missing or the texture is stretched
or corrupted. When I draw a square with no texture, part of the square
is missing sometimes.

I do not see a pattern to when it works and when it doesn't. It might
be broken one run, then after a back button and rerun, it works the
next.

The triangle that's missing is not one of the triangles used to draw
the square. Rather it is part of the first triangle and part of the
second triangle. The triangles are the bottom right half and the top
left half of the square, but the part missing is the bottom left half
of the square.

The problem occurs on both the Droid and on the emulator.

--due to Google Groups Error, I can't post any more. I'll try to add
the details in another post--
