It always flashes because 1) there's no synchronization between resizing and flipping and 2) there are two resizes immediately after each other (one for each axis). Resizing via application is much better because 1) the application can make sure that the window content is correct before the next flip would occur, 2) mouse movements can be compressed causing a single resize only. I would like to integrate this handling into a window manager core module which would run in each application. > I've also ported freeglut to DirectFBGL. freeglut is a full featured GLUT > implementation and it draws menus and text using OpenGL so it's mostly > windowing system independent.
