OK, I'm one step further and found out which packages to downgrade to prevent that strange frame/border around Gnome-windows-problem:
The following downgrades prevent the problem: Downgrade of gtk3 (3.16.1-1 => 3.14.9-1) Downgrade of nautilus (3.16.0-1 => 3.14.2-2) Downgrade of totem (3.16.0-1 => 3.14.2-1) I found it by downgrading Nautilus at first. The problem kept appearing, in terminal was the message: (starting nautilus 3.16) $ nautilus (nautilus:3652): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:2:19: Theming engine 'adwaita' not found (nautilus:3652): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files Initializing nautilus-dropbox 2.10.0 <IntrospectionModule 'Nautilus' from '/usr/lib/girepository-1.0/Nautilus-3.0.typelib'> Insync Nautilus Plugin <class 'insync_plugin.InsyncExtension'> Socket: /run/user/1000/ownCloud/socket <=> /ownCloud/socket Socket File: /run/user/1000/ownCloud/socket Setting connected to True Socket watch id: 16 ('[__init__ insync plugin]', <InsyncExtension object at 0x7f349237bd70 (uninitialized at 0x0)>) sys:1: Warning: The property GtkSettings:gtk-button-images is deprecated and shouldn't be used anymore. It will be removed in a future version. sys:1: Warning: The property GtkSettings:gtk-menu-images is deprecated and shouldn't be used anymore. It will be removed in a future version. That made me think of downgrading gtk, in which I was right and wrong at the same time: The frame-around-windows-problem disappeared, but the waring starting nautilus stayed: starting nautilus 3.14: $ nautilus (nautilus:5174): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:2:19: Theming engine 'adwaita' not found (nautilus:5174): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files Initializing nautilus-dropbox 2.10.0 ImportError: No module named Nautilus (nautilus:5174): Nautilus-Python-WARNING **: nautilus_python_init_python failed (nautilus:5174): GLib-GObject-WARNING **: The property GtkSettings:gtk-button-images is deprecated and shouldn't be used anymore.
