--- Comment #10 from Florian Link <florianlink at gmail.com> ---
Sorry, seems that the trace I attached did not have the right angle.

I did another trace and used the 64bit glretrace with Mesa LLVMPipe (10.2 RC2)
opengl32.dll (64Bit) copied to the apitrace-msvc\x64\bin. I then get two red
pixels on the top left corner of the black cube, which are from the red
backface.
I tried both release and debug Mesa dll, both show the problem.

I also did the test with an older Mesa LLVMPipe (10.0 dev), and it showed 3 red
pixels instead of 2. Running it with softpipe shows not errors.

Will attach the trace in a sec.
