Hoster screen flashing on & off with 3.313

[bryant]

Slowness is really funny, sort of happens randomly, but not very often anymore. And always with no other programs runnung. I do remember my g/f saying when it started; it was right after 3.312(or somewhere around there). It would get really bad at first too. Real slow redraw every time the search box was closed, either using "close" of the right corner "x" buttons.

I think we need more evidence of redraw, slowness, and precise conditions from others and maybe we can get this figured out.
