I am attempting to create a multisample pbuffer for FSAA'd off-screen rendering. Now, you can pass GLX_SAMPLE_BUFFERS_ARB into glXChooseVisual() of course.. but you cannot pass it into glXChooseFBConfig(), and then call glXCreatePbuffer() (GLX1.3) with the frame-buffer config.
There is probably a simple work-around for this, but I can't see it ATM. Any suggestions?
Thanks in advance,
