I have written a MS Windows MDI app that uses OpenGL-based views. I have noticed lately that when I toggle the maximize on my window, a black edge appears around one or
more edges of the window. I’m not sure what is happening here. I clear the color buffer, but it’s almost like the color buffer doesn’t take up the entire window. I have narrowed this down to instances where I use the OpenGL selection mechanism in order to do box selection. Any ideas on what causes this?
