As it turned out, the reason for that was Xorg starting in rootless mode and apparently not initializing everything properly, which was causing gnome-shell/libmutter to crash. Installing xserver-xorg-legacy did partially fix those issues. Enabling modesetting for nvidia driver however still causes the problem.
