Dear XQuartz dev,
<br>
<br>I have an application that crashes on Lion 10.7.5 and Mountain Lion 
10.8.* with the error : &quot;Error: GLwMDrawingArea: requested visual not 
supported&quot;.
<br>
<br>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 &quot;glxinfo&quot; output from OS X 10.7.4 with the one from OS X 10.7.5)
<br>
<br>So I have a few questions :
<br>  - Is there an easy way to work aroud it ?
<br>  - Where do I have to report this bug ? Apple ? XQuartz ? OpenMotif ?
<br>
<br>Best regards,
<br>Rafael Navaza.
