"Web1 de jun. de 2024 · 1 Answer Sorted by: 1 The functions gluOrtho2D and glOrtho multiply the current matrix by the new orthographic projection matrix. This causes that if the reshape is called a 2nd time, the matrix which was set by gluOrtho2D before, is multiplied by the new one and you get consecutive changes. " - Opengl reshape
