This gdk_display_sync() call was added in commit a40daa3c22 so the alt-f2 dialog is able to spawn commands that trigger grabs on startup (eg. xmag/ xkill). This seems worthwhile to do only on the X11 backend, and handling it in mutter backend code seems cleaner. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/317
