Ruby Forum Ruby-Gnome 2 > Gdk::Pixbuf#from_drawable Memory Leak?

Hey,

I have been having problems with using Gdk::Pixbuf#from_drawable - it
seems to leak memory (see example below).

Is this a (known) bug? Is there a patch/workaround?

Regards,
Andy.


require 'gtk2'
require 'gtkmozembed'

Gtk.init

gtk = Gtk::Window.new

moz = Gtk::MozEmbed.new
moz.set_chrome_mask(Gtk::MozEmbed::ALLCHROME)

gtk.add(moz)
gtk.maximize
gtk.show_all

moz.load_url("http://www.google.com/")

Gtk::timeout_add(1000) do
        x, y, width, height, depth = gtk.window.geometry

        pixbuf = Gdk::Pixbuf.from_drawable(nil, gtk.window, 0, 0, width,
height)
        pixbuf = pixbuf.scale(640, 400, Gdk::Pixbuf::INTERP_BILINEAR)
        pixbuf.save("foo.png", "png")

        GC.start # This doesn't help :(

        true
end

Gtk.main
