https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1024482 gives plenty insight into the behaviour. Especially Daniel Gnoutcheff's comment https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1024482/comments/15.
The following env variable solves the problem. At least with the #if condition from above applied. I haven't reverted it yet.
g_setenv ("GDK_CORE_DEVICE_EVENTS", "1", TRUE);
