Hi,
This is probably related to the space occupied by the TITLE area and in
which callback you are using to draw. Can't tell you what's the best
solution with just that information.
To draw elements aligned with IUP elements inside a IupGLCanvasBox, I
suggest you to use an IupGLSubCanvas element. You will be able to draw from
0 to rastersize in its GL_ACTION callback. Use the layout positioning to
align the element inside the glframe.
Best,
Scuri
