In my case, I'm using the nvidia driver. I doubtful that its a threading issue. My program is threaded, but I only use one thread for OpenGL. I'm suspicious that its a bug having to do with the use of 'XmuLookupStandardColormap()'. For one thing, the bug is persistent for the life of the Xserver process, and its caused by a bad Colormap id being set on the window by this function. I can't find much documentation about this function. Since its persistent, it could very well be an Xserver bug. Perhaps its not such a good idea for gtkglext to be using it? -bryan _______________________________________________ gtkglext-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkglext-list
