The issue is back.


run xpdf on a document which large regions of black and white, and
flip between pages.

It looks like something is cached and not being
pushed/invalidated/writethrough.  so it does not make it onto the
screen correctly.  there are cache-streaks which don't update on an
idle machine.

If the machine is very busy, it is hard to see these because the cache
lines get pushed earlier.

But on an idle machine, documents are unreadable.
