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 --Jeremy On Jan 9, 2013, at 8:28 AM, Frava <fravadona@gmail.com> wrote:
Dear XQuartz dev,
I have an application that crashes on Lion 10.7.5 and Mountain Lion 10.8.* with the error : "Error: GLwMDrawingArea: requested visual not supported".
By playing a little with the source code of that application I figured out that OS X 10.7.5 and 10.8.* do NOT support the GLX Accumulation Buffer anymore (You can check it by comparing the attached "glxinfo" output from OS X 10.7.4 with the one from OS X 10.7.5)
So I have a few questions : - Is there an easy way to work aroud it ? - Where do I have to report this bug ? Apple ? XQuartz ? OpenMotif ?
