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

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 ? Best regards, Rafael Navaza.
