Hi,
testing a octave/fltk graphics issue, I noticed that also the
demo of fltk with GL interface has a similar issue.
On http://matzeri.altervista.org/works/fltk_gl/
I uploaded the before and after apperance of "gl_overlay" demo.
It is enough to move the window to loose the geometrical
image while the bars are correctly re-drawn.
Running Xwin with -wgl does not show such defect, but it is
terribly slow. So I assume it is not a fltk defect but of
GL or XServer.
A copy of gl_overlay from fltk-1.3.1.9857-1 build is also uploaded.
Regards
Marco
further experiment showed that the defect is present when the integrate
windows manager is used. With external window manager (fvwm, openbox,..
) that defect does not apper.
With external window manager another defect appears, the upper
bar effect is not shown at all; while it is present on the integrated
window manager.
Regards
Marco
