Public bug reported:

Binary package hint: firefox-3.0

When i type something in a multi-line form (like on Wikipedia) Firefox
becomes very slow. It takes a while until the text I am typing appears
in the form. There is a visible gap betwen key pressed and the character
showing on the screen.

I have same behavior on Epiphany.

I suspect this may be related to compiz or X rather than browser
(xorg.conf attached).

I tried to "reset" gnome (rm -rf .gnome .gnome2 .gconf .gconfd
.metacity) with no visible effect on the problem.

Ubuntu 8.10 64bit
