Comment # 16
on bug 91993
from Nicolai Hähnle
The bug is caused by the combination of a (technically correct, but unintentional) off-by-one problem in AstroMenace with a bug in the Mesa state tracker. (Old versions of) AstroMenace use glTexStorage2D to create a texture with an incomplete mipmap pyramid (the 1x1 level is missing). This pyramid is not honored by the state tracker's implementation of glGenerateMipmap, which results in various broken textures. Current versions of AstroMenace no longer have the off-by-one problem, which is why Marek could not reproduce the bug. I'm working on a Piglit test and Mesa patch to fix the bug on our side.
