I'm setting a transparent PNG as a drag icon:
pixbuf = gtk.gdk.pixbuf_new_from_file('image.png')
ev_box.drag_source_set_icon_pixbuf(pixbuf)
As soon as I begin a DND operation the transparent parts of the image start flickering. This happens only on a Linux test system (CentOS). On Windows everything is fine.
Is there a fix or a better workaround than not using a transparent image?
