Public bug reported:

I've notice in both Nautilus and Evolution that when the screen content
exceeds the viewable space, often simple interactions (render email
preview, directory in list few with many files) force compiz to spin one
core at about 20%, sometimes for a minute or two and the current window,
and any other with pending work to *figure out* a vertical scroll just
sit in the greyed wait state.

It is really apparent when opening my Nautilus home directory, as this
operation usually a few seconds, but since recent 11.10 seems to take
about a minute.   Often when the Nautilus window is greyed out, the
vertical scroll is missing. This observation and  one from an upstream
Evolution thread that noticed ithe delay only happens with vertical
scroll in the preview is what has led me to believe there is some issue
with the vertical scroll bar calculation/display.

One workaround may be to use a giant screen and orient the the long axis
vertically to cut down on the need for vertical scroll bars altogether
or organize Nautilus icons to reduce the need for vertical scrolling and
increase Evolution mail preview space.
