Here is how I ask the multisampled framebuffer:
GLint visual_attribs[] = {…, GLX_SAMPLE_BUFFERS, 1, GLX_SAMPLES, 4, …}
glXChooseFBConfig(…, visual_attribs, …)

This sample code works properly on standalone Xorg, on the exact same configuration.

Mesa 11.2.0_devel commit 3e8f644 (I can reproduce on 11.1.0), Xorg 1.18.0, on an up to date ArchLinux.
