Comment 21 for bug 125970

Just switched to the 25 August nightly of Firebird (from 6.1) and noticed that
things have slowed back down. A lot.

Anyway... this shows up both on Windows and OS X, so I'm betting Linux/Unix have
it too. Curiously, though, on Mac OS, having transparent or hovering windows
doesn't have much to do with it.
