    initial v1  
    1 This is a somewhat common Linux problem glDrawBuffer(GL_BACK) fails.  In this report we see ISOLDE also can create an OpenCL context.  Not sure if that is a symptom of the same problem.  Don't know what causes this, only ever seen on Linux (about 10-20 times), although I have long suspected that Linux may invalidate the OpenGL context for unknown reasons and we have no code to recover from that.
