If there's a single small window (e.g. empathy chat) in the overview, it looks usable, because it's as big as outside of the overview, but when you start to type, overview search is launched, which is confusing. Fix that by setting maximum scale for window clones to 0.7 https://bugzilla.gnome.org/show_bug.cgi?id=646704
