Hi, and welcome me to the group :P
The title might be misleading, but I'm experiencing weird behavior using GNOME3 desktop under Debian 3.16.0-amd64, in that some disk operations and things like generating keys, have delayed feedback, for example, I create a key, Documents collection, and such, and nothing happens, until a couple of minutes later, by which time I've tried several times, and it turns out every time I succeeded. But there was no feedback. I guess I'm a newbie...
