I'm trying to use a background thread to draw into a view using opengl. Doing anything GL-related in a secondary thread segfaults, however. Poking around AppKit and the X11 backend, I note that GSCurrentServer() is returning NULL on every thread except the main one. I know that secondary threads are not supposed to do any drawing, but this prevents me from even making a context with shared state, drawing into a PBO, and then blitting that into the view in the main thread.
Any suggestions?
