Iff a character is in specific areas some textures on him are not rendered. In
the entry of colony 9 is such an area.

The textures are rendered properly on the Intel GPU.

There are screenshots, a fifolog and an apitrace at the end of the linked
bugreport.

The problem appears in Debian Jessie, Sid and mesa-git the last time checked,
which was 9 days ago.

I compiled mesa-git with

CFLAGS = -g -O2 -Wall -std=c99 -Werror=implicit-function-declaration
-Werror=missing-prototypes -fno-strict-aliasing -fno-builtin-memcmp -DDEBUG

and set

$ export LIBGL_DEBUG=verbose
$ export MESA_DEBUG=1
$ export EGL_LOG_LEVEL=debug

before running dolphin. Running dolphin with the game until the issue appears
gives the following output

$ dolphin-emu

I'm sorry, I don't know how to write a simple GLUT-based test program.
