Comment # 4 on bug 93292 from 
I uploaded a new apitrace with low details settings and disabled intro video,
which makes it much smaller (170 MB xz).

While I was at it I played a bit with qapitrace, comparing the r600 and swrast
output. And I found the origin of the bug.

The "breaking" call is "1247216" in the new trace:
  glDrawElements(mode = GL_TRIANGLES, count = 600, type = GL_UNSIGNED_SHORT,
indices = NULL)

The call "destroys" the depth map, filling it with a constant value, so nothing
is rendered.

Actually I suspect the glUseProgram(87) in call 1247202 to be the origin of the
problem, as it installs a shader program (AFAIK OpenGL) and because I'm able to
play Thea using the llvm r600 backend via "R600_DEBUG=llvm" and if I disable
"ambient occlusion", which is also broken.

My current mesa build is based on commit
6303231a1ddf646b05c43c6bbc7fa71314ebb3fc
