Hi all! We are developing an application which uses the GtkGLArea to embed an OpenGL Performer window into a GTK user interface. The application is able to display the 3D-scene in mono or in stereo. Some time ago, when we were still using GTK 1.2, this worked fine. In the meantime we ugraded to GTK+ 2.2.2, so I had to upgrade the GtkGLArea too. Now I noticed that stereo mode doesn't work anymore. I'm not quite sure, that this is a GTK problem, since there were other program changes. But after running some simple test cases it looks like there is a problem with the GLContext. First I create the GtkGLArea with attributes for quad buffered stereo. This works on a machine which is configured for stereo display. On a machine without stereo visuals it fails and returns a NULL pointer. So far so good. Then I connect the performer window to it. When this window is opened I test whether stereo is available. This test fails, so it looks like the stereo attribute is somehow lost. The drawing calls are executed for buffers GL_BACK_LEFT and GL_BACK_RIGHT, but I get only a mono display. On the same machine another application which doesn't use GTK can successfully display a scene in stereo. Has anyone else experienced problems with stereo mode?
