[Xquartz-dev] Is the GLX Accumulation Buffer broken ?

[Jeremy Huddleston Sequoia]

Your glxinfo output is from two different graphics cards.  Your "working" copy was using:

OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon HD 6970M OpenGL Engine
OpenGL version string: 2.1 ATI-7.18.18

Your "failing" copy was using:

OpenGL vendor string: Intel Inc.
OpenGL renderer string: Intel HD Graphics 3000 OpenGL Engine
OpenGL version string: 2.1 APPLE-7.32.12
