[Tom Goddard]

This is quite interesting as I've seen this Linux glDrawBuffer(GL_BACK) invalid operation error reported dozens of time but never saw the "The X11 connection broke (error 1). Did the X11 server die?" message. Possibly when the X11 server disconnects this glDrawBuffer(GL_BACK) call is the first place our code fails. That would explain why I have only ever seen this OpenGL error on Linux.

[Greg Couch]

Sometimes the graphics driver crashes taking the X11 server with it.
