Comment= # 8 on bug 96512<= /a> from Nicolai H=C3=A4hnle 
I believe that this is a game bug.

Some of the black objects are rendered in draw calls between 526669 and 526=
714
of the provided trace. They're using program 2823, which contains fragment
shader 2811, which uses a shadow sampling instruction on sampler 15, but the
texture bound to texture 15 is a 1x1 GL_SRGB texture.

The GLSL 4.50 spec in the section on Texture Functions says: "If a sha=
dow
texture call is made to a sampler that does not represent a depth texture, =
then
results are undefined." -- that is, the game is invoking undefined beh=
aviour,
hence this is not our bug.
