I'm not sure if it is or not. I don't notice any difference with the
toolbar enabled or disabled. I keep it disabled by default.
It happens with the NS port. I haven't tried GTK+ / Xaw. It doesn't
seem to happen if I run Emacs in a terminal. If I launch NS Emacs,
then connect to it with emacsclient, I still get the problem. It
happens whether the buffer is visible on the text frame, the GUI
frame, or both.
It occurs when flyspell-mode is enabled in any buffer. The major mode
doesn't matter.
It recently got mush worse, to the point where I must disable flyspell
in erc-mode to maintain my sanity. I suspect it was the 2009-03-14
commits to src/nsterm.m src/nsfont.m etc.
