This is just generally a good idea. I believe this is a freeglut bug. Kilgard's GLUT came first and the behaviour of window reshaping is documented here: http://www.opengl.org/resources/libraries/glut/spec3/node48.html#SECTION00083000000000000000 according to that, the reshape function should always get called at least once when the window first appears. -- You are receiving this mail because: You are the assignee for the bug.
