Description
After upgrade to gnome 3.16 with gnome-shell 3.16.1-2 and gdm 3.16.1.1-1 on archlinux, also with previous 3.16 versions, after I suspend to ram for some time and resume from it, the gdm window freezes and cannot input. After some tty switching using ctrl+alt+f1/f2/f3, the login window becomes usable slowly. And after I unlock it with password, the desktop and running applications shows just fine on tty2. But now when I switch to tty1, there is still a gdm login screen, if I login into it, tty2 shows, and switching to tty1 the gdm login is still there, still usable.
Not everytime I suspend it happens. It seems to be more reproduceable after long suspend time. For example, a suspend time of 20 hours.
