During redesign terminal decoration was removed which left terminal with light background color. This restores terminal with dark background color & other minor tweaks. These tweaks needs to be modified again for GTK >=3.19.3, but for now it works.
GTK+ Places Sidebar in 3.18.x uses GtkLIst Box which is used by Nautilus and GtkFileChooserDialog. This fix adds padding in GtkPlacesSidebar widget. That way icon padding remains constant across all sidebar widgets.
Previously, background color of left, right and bottom part of windows are set transparent.This was making titlebar appears 1px wider than the window itself.This fix only affects those apps which are patched by ubuntu to use traditional titlebar over headerbar.
This commit adds CSS rules to theme undershoot and overshoot. This is
what some applications use to indicate that there is more content below
and/or above the current content viewport.
This is notably used for Nautilus. Without those styles, those classes
are shown as an opaque gray area which looks bad and hides information.
