Comment # 4
on bug 93292
from Jan-Marek Glogowski
I uploaded a new apitrace with low details settings and disabled intro video, which makes it much smaller (170 MB xz). https://docs.google.com/uc?id=0Bwde9zQo1PeCVVdZU2ZSM3hKcXc&export=download 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
