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/](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
