Comment 3 for bug 1488183

when I typed wallpaper at the elementary os git repo no results were shown then I typed screen and this came up.

I notice the first is a login screen

inherit gnome2-utils vala cmake-utils

scroll bar:

DESCRIPTION="Overlay Scrollbars use an overlay to ensure that scrollbars take up no active screen real-estate."
HOMEPAGE="https://launchpad.net/overlay-scrollbar"0.

arrow patch:

 menu_parent.app_paintable = true;
menu_parent.set_visual (Gdk.Screen.get_default ().get_rgba_visual ());

screen resolution:

- public string screen_resolution { get; set; }
- public GalaSettings gala_settings;
-
- public Settings () {
+ public bool use_category { get; set; }
+ public string screen_resolution { get; set; }
+ public GalaSettings gala_settings;

*******************************
would any of these factors possibly contribute to the memory leak?
