Gdk::Pixbuf.new direct before cell.pixbuf.fill! seems to help. I am not
really sure, tested only for a few minutes yet.

cell.pixbuf = Gdk::Pixbuf.new(Gdk::Pixbuf::COLORSPACE_RGB, true, 8, 10,
10) # (colorspace, has_alpha, bits_per_sample, width, height)
cell.pixbuf.fill!((iter[Col_R] * 255).round * 16777216 + (iter[Col_G] * 255).round * 65536 + (iter[Col_B] * 255).round * 256 + (iter[Col_A] * 255).round)


Before that, I tried to use cairo instead of pixbuf.fill like


s = Cairo::ImageSurface.new(Cairo::FORMAT_A1, 3, 3)
cr = Cairo::Context.new(s)
pixbuf = Gdk::Pixbuf.from_surface


Gdk::Pixbuf.from_surface() method seems to be not available?
