Linux, Ubuntu Gutsy, -intel (945GM chipset).
Initially with mesa 7.0.1, then I tried a later mesa version, 7.0.2
which I back-ported from Ubuntu Hardy. I've now built GIT HEAD mesa, and
still have the issue.
Let me check up and see if I can fix it by ordering the data as was
suggested by David Thompson, if not, I'll put some screenshots online.
glxinfo output (the TTM buffer manager is a red herring, due to mixing
GIT HEAD mesa, libdrm and kernel dri code with an older X server if I
understand correctly.)
name of display: :0.0
[intelInitDriver:523] Failed to init TTM buffer manager, falling back to
classic.
