I guess you're right about that (for some definition of normal):

There is no mouseover problem in Emacs 24.3 or prior, but the flickering
of the menu bar is there.  However, there is no such flickering with
Emacs 20 at all.  (I no longer have Emacs 21, so AFAICT the flickering
problem starts with Emacs 22.)
