Comment 15 for bug 155002

I am still aware of the issue. It has been alleviated by X-Fixes being less of a problem, partly because FireFox doesn't have an animated cursor any more.

The defaults have been changed and a software cursor plus mouse panning is now the default, which means this isn't a problem with the default configuration - though most likely a problem if you explicitly reset the option.

The defaults are not fixed in maverick to my knowledge, though I must confess to not checking. I only changed them upstream about two months ago.
